As most of you already know, we've run a few HPP Pavement Pounder Shootouts at Norwalk Raceway Park (NRP) in years past. The combination of location, quality of the facility, and the expert track prep make it a great choice for the variety of Pontiacs we cover. If anyone is going to hook up and run their best 60-foots, it's likely to happen at Norwalk. NRP is also home to the Ames Performance Pontiac Nationals, the largest Pontiac event in the nation. As such, it attracts a huge number of Pontiac racecars, making it easy for us to coordinate racers to feature. Over the past few years, HPP's editor and Pete Woodruff of Super Duty Promotions casually discussed the possibility of a shootout to coincide with the Ames Performance Pontiac Nats at the famed facility. Then Bill Bader Jr. called to say the track was interested in having HPP host a shootout, and Bill and Pete even had the date in mind: the Thursday before the Ames Performance Pontiac Nats. How could we refuse a chance to do another shootout on a well-prepped track at the invite of the track owner? With the help of Bill and the staff at Norwalk Raceway Park and Super Duty Promotion's Pete and Andrea Woodruff, the event came off without a hitch. Everyone had plenty of time to make as many passes as they wanted, even with the threat of rain coming in the late afternoon. We had a total of 16 cars participate, though this time, there were several others who couldn't make it to the starting line for one reason or another. Not to worry, we always try to reschedule. Speaking of the weather, it was much like one expects in northern Ohio in early August: hot and hazy with a high temperature of 92 and a relative humidity of 47 percent. It was cooler in the morning, but by the afternoon, when most of the runs were made, the effective elevation reached 3,900 feet, which receives a correction factor of 0.9523 for e.t. and 1.0507 for trap speed. The Strip Tuning Log includes the correction for the best pass only (based on e.t.). To convert the other runs, multiply the e.t. or mph by its factor to arrive at the corrected figures. For our first installation of the Norwalk shootout, we present four traditional Pontiac racecars, all quite different in approach but all sporting 455 power in some form. The combinations are mild to wild and include Portland, Michigan's Dan Jensen and his Pure Stock Drags-prepped '71 T-37; Topeka, Kansas, natives Kevin and Deloris Constant with their tube-frame and street-legal '85 Grand Am; Lorin and Greg Budzinski's street/strip '81 Grand Prix; and Larry Snyder's race-only '77 Firebird Formula. Owner Bio: Dan Jensen Anyone who's been in the Pontiac hobby sometime during the last 20 years has most likely heard of Portland, Michigan's Dan Jensen. Dan and Bob Boden have been running the Pure Stock Musclecar Drags. Held annually at Mid-Michigan Motorplex in Stanton, Michigan, the "Pure Stocks," as they are known, have become a great place for musclecar fans of all marques to come together and race. Visit www.purestockdrags.com for info on this year's event. Dan, 49, has been racing for the last 30 years, and after 22 years as an accountant for TRW, he now builds and restores engines for musclecars. His T-37 is a clone, built so he could retire his original 455 H.O.-powered '71 T-37 post coupe from active racing. "I had my eye open for another post coupe so I could clone it as a 455 H.O. car, and in the fall of 2004, I bought this 350 two-barrel automatic coupe," he says. "I consider these '71 455 H.O. T-37s to be Pontiac's late-model lightweights." In addition to the two T-37s and his first car, a '71 GTO, he also has Jim Mattison's '95 Firebird Formula show car, a prototype of the '95/'96 Comp T/As and WS-6 Firebirds. Additionally, he owns an '05 GTO and is cloning a '69 350 H.O. Tempest coupe. Past Pontiacs include a '70 R/A-IV Judge; a '71 455 H.O. LeMans (1 of 3); a '74 SD-455 T/A; a '74 SD-455 Formula; a '70 four-speed 455 Grand Prix; and a '72 "GTO'd" 455 H.O. station wagon. | Strip Specs | | Year/Model: | '71 T-37 cloned as a 455 H.O. | | Race Weight: | 3,685 lbs | | Curb Weight: | 3,535 lbs | | Type of Fuel: | 93-octane unleaded | | Engine: | YC-code 455 | | Cubic Inches Before/After Bore: | 455/462 | | Built By: | Dan Jensen | | Carburetor: | Q-jet 7041263, 0.073 jets, 0.043 primary metering rods, G-hanger, "CR" 0.0547 secondary metering rods | | Spacer Plate: | None | | Intake Manifold: | Stock 455 H.O. | | Fuel System: | Stock full-canister mechanical pump, factory 3/8-in lines | | Heads: | '71 #197 round-port, no porting | | Flow Numbers: | N/A | | Valves: | Stock 2.11/1.77 two-piece | | Pistons/Rings: | Speed Pro forged 4.180-in/file-fit moly | | Rods: | Eagle forged-steel, stock 6.625-in | | Compression Ratio: | 9.40:1 | | Crankshaft: | Stock 455 nodular-iron | | Rotating Assembly Balanced: | Yes | | Camshaft: | Cam Motion hydraulic | | Camshaft Specs: | 212/225-deg dur. at 0.050, 0.415/0.413 lift | | Camshaft LSA: | 112-deg | | Camshaft Centerline: | Intake ground at 110-deg | | Installed Position: | Retarded 4 deg. to work better with 3.73 gears | | Rocker Arms: | Factory stamped-steel 1.50:1 | | Ignition: | Stock distributor with PerTronix Ignitor conversion, Pertronix coil, reproduction date-coded wires, AC R45S spark plugs | | Total Timing: | 37-deg all in by 2,500 rpm | | Exhaust: | 455 H.O. manifolds, 2.5-in pipes, x-type crossover, MagnaFlow mufflers | | Power Adder: | None | | Transmission: | Turbo 400, mild shift improvements | | Converter: | Stock GM Turbo 350 12-in | | Shifter: | Original column shift | | Rear: | GM 12-bolt housing, Safe-T-Track, 3.73 gears | | Brakes F/R: | Manual 9.5-in drum | | Wheels F/R: | Chevy/Olds 14x7 code-XT steel | | Tires F/R: | Coker Firestone G70x14 reproduction | | Tires Pressure F/R: | 45 psi/40 psi | | Suspension Fr: | Factory stabilizer bar, coil springs, shocks, and rubber bushings | | Suspension Rr: | Factory springs, shocks, trailing arms, and rubber bushings | | Chassis Mods: | None | | Interior Mods: | Factory in-dash tach and gauges replace the standard warning lights | | Exterior Mods: | 455 emblems and H.O.

Owner Bio: Deloris and Kevin Constant A great example of a late-model Pontiac body style that really stands out in the crowd as a racecar is Deloris and Kevin Constant's (shown with daughter, Mary) '85 Grand Am. Looking to all the world like a retired Pro-Stocker from the '80s, the Grand Am was actually built because the Topeka, Kansas-based racers wanted a smaller racecar for Deloris to drive. The combination of lightweight tube-frame chassis and torquey 455 have made for a quick, reliable racecar that is still street-driven, even featuring a working horn, wiper, lights, and so on. When not on the track, the Grand Am is driven to Cruise Nights in the Topeka area. Deloris relates her favorite moment in this car: "Winning my first quick 16, which happened to be on Father's Day, so it was the best gift I could have given to my husband." She's been racing for 12 years, learning the ropes on a '68 GTO. The Constants also wish to thank Todd Whorton, Fidler Machine, Motorparts Mike, and Kauffman Racing Equipment for their help getting the Grand Am to where it is now. In addition to it and the GTO, the couple also owns a '70 GTO; a '69 Grand Prix; a '68 LeMans; an '88 Grand Am; and a '99 Bonneville. | Strip Specs | | Year/Model: | '85 Grand Am | | Race Weight: | 2,950 lbs | | Curb Weight: | 2,800 lbs | | Type of Fuel: | VP C12 | | Engine: | '75 455 | | Cubic Inches Before/After Bore: | 455/462, four-bolt main caps and studs added | | Built By: | Dave Campbell at Fidler Machine in Topeka, Kansas (Kevin Hall owner) | | Carburetor: | 1090/4500 series removable sleeve Demon, jetted 94-square, no power valves | | Spacer Plate: | None | | Intake Manifold: | Edelbrock Victor 4500 series | | Fuel System: | 2 Holley Blue pumps and 2 regulators, set at 8 psi (one for each bowl on the carburetor) 6 AN fuel line | | Heads: | Edelbrock aluminum 72cc, ported by KRE | | Flow Numbers: | N/A | | Valves: | 2.11/1.66 Ferrea stainless | | Pistons/Rings: | Ross 4.180, plunge-cut dome/Total Seal Gapless | | Rods: | GRP aluminum, stock 6.625-in | | Compression Ratio: | 13.7:1 | | Crankshaft: | Eagle cast-steel 4.21 stroke, rotating assembly balanced | | Camshaft: | Ultradyne solid roller | | Camshaft Specs: | 271/278-deg dur. at 0.050, 0.626/0.626 lift | | Camshaft LSA: | 108-deg | | Installed Position: | 104-deg | | Rocker Arms: | Crane 1.50:1 roller | | Ignition: | Gutted HEI with MSD control, 6-AL box, Taylor wires, Autolite #3924 plugs | | Total Timing: | 38-deg all in by 3,000 rpm | | Exhaust: | 2-in primary headers 3.5-in collectors built by Homemade Performance, coated by AirBorn, 3.5-in pipes, Duramax mufflers | | Power Adder: | None | | Transmission: | Powerglide with transbrake, performance built, cooling-line pressure-reduction valve | | Converter: | Richard Doherty 8-in bolt-together, 5,400-rpm stall | | Shifter: | Hurst Quarterstick | | Rear: | 9-in Ford, 4.11:1 gears, Auburn spool, Moser 35-spline axles | | Brakes F/R: | '78-'87 GM metric spindles, 10.9-in rotors, calipers/10.9-in rotors with 3-in steel hats and GM metric calipers | | Wheels F/R: | Weld Draglite 15x3.5/Weld Draglite 15x12 (3.5-in backspace) | | Tires F/R: | Off-brand 135/75SRx15/Hoosier 29x12x15 slicks | | Tire Pressure F/R: | 40 psi/10.5 psi | | Suspension Fr: | 90/10 RCI coilover shocks with 400lb springs, Corvette aluminum A-arms, no stabilizer bar, Pinto rack-and-pinion steering | | Suspension Rr: | Three-link with third link mounted on top of rear end, Strange double adjustable shocks (right-side compression #10, rebound #6; left-side #7 compression, rebound #7) with 130lb springs | | Chassis Mods: | NHRA certified to 8.50 ET mild-steel by Homemade Performance | | Interior Mods: | Aluminum racing seats, electric windows and locks, custom sheetmetal, full carpet, headliner | | Exterior Mods: | Fiberglass cowl scoop on hood, Lexan windshield | | Safety Mods: | Full chassis and rollcage certified to 8.50 e.t.

Owner Bio: Lorin and Greg Budzinski Many fathers dream about building a racecar with their son as a means to further bond their relationship and experience the thrill of racing together. Lorin Budzinski, 57, a retired crime-lab scientist for the Detroit Police Department, and his 34-year-old son, Greg, have joined forces to build a 455-powered '81 Grand Prix that hooks up, runs hard, and is easy to maintain. It was chosen as an inexpensive alternative to the GTOs and Firebirds more commonly seen at the strip. Building on the torque characteristics of our favorite undersquare V-8, the pair have hit on a simple, low-rpm engine that uses as many off-the-shelf parts as possible. It was originally built as a street engine for Lorin's '64 2+2, but it seemed like such a natural for this project that it was used for the Grand Prix. "This car is special to me because it represents a true team effort on the part of my son and myself," said Lorin, who has Greg do the driving. "It's the most fun we've had together since he was in Little League." He continued, "When people see the car run, they're surprised that there isn't a nitrous bottle in addition to the Pontiac engine." In addition to the Grand Prix and the 2+2, the Budzinskis have a '63 Catalina two-door post sedan. Lorin also drove a '68 GTO in the early '70s with a 421 Super Duty that ran 12.20s at 112 mph. He drove it to work for a couple of years but decided the race car could cause a conflict with his police job, so it was retired from street use. | Strip Specs | | Year/Model: | '81 Grand Prix | | Race Weight: | 3,475 lbs | | Curb Weight: | 3,265 lbs | | Type of Fuel: | 93 Octane | | Engine: | '74 YU-code 455 | | Cubic Inches Before/After Bore: | 455/466 | | Built By: | Lorin Budzinski | | Carburetor: | 830 Holley DP, jets #86 square | | Spacer Plate: | 1-in, four-hole phenolic | | Intake Manifold: | Edelbrock Performer RPM | | Fuel System: | Holley 110-gph with Holley regulator set to 6.5 psi, Fram fuel filter, 1/2-in aluminum line to regulator, then -8 AN lines to carb | | Heads: | Edelbrock 87cc, port-matched and pushrod-bulge opened up | | Flow Numbers: | Close to stock Edelbrock | | Valves: | 2.11/1.66 SI from Edelbrock | | Pistons/Rings: | Ross forged 4.180/Total Seal Gapless | | Rods: | Eagle forged 6.800-in | | Compression Ratio: | 10.2:1 | | Crankshaft: | Nodular-iron, stroked to 4.25 in | | Rotating Assembly Balanced: | Yes | | Camshaft: | Comp Cams street mechanical roller, Magnum series | | Camshaft Specs: | 244/255-deg at 0.050, 0.585/0.555 lift | | Camshaft LSA: | 106-deg | | Camshaft Centerline: | 112-deg | | Installed Position: | 6-deg advanced | | Rocker Arms: | 1.65:1 Crane Energizer intake, 1.50:1 Omega (JBP) exhaust | | Ignition: | Stock cast-iron Pontiac dist, Mallory electronic conversion, ACCEL 300 wires, Autolite #3924 plugs | | Total Timing: | 34-deg all in by 2,200 rpm | | Exhaust: | Indian Adventures 17/8-in primary headers, 3.5-in collectors, 3-in pipes, Dynomax welded mufflers | | Power Adder: | None | | Transmission: | Turbo 400, performance rebuild, full manual-reverse shift pattern | | Converter: | Coan 10-in, approx 3,000 stall | | Shifter: | B&M | | Rear: | Ford 9-in, Currie housing and axles, truck centersection, Detroit Locker 3.50:1 gears | | Brakes F/R: | Stock 10.9-in disc/9.5-in drum | | Wheels F/R: | 15x4 ET slots/15x7 Ansen slots | | Tires F/R: | Syntread 165/75Rx15 / M/T ET Street 28x11.5x15 (27.3 tall x 8.6 wide) | | Tire Pressure: | 40 psi/23 psi | | Suspension Fr: | Stabilizer bar removed, stock V-6 springs, CE shocks (80/20) | | Suspension Rr: | CE shocks (50/50), stock springs, Southside Machine trailing arms | | Chassis Mods: | Six-point rollcage | | Interior Mods: | Lightweight buckets, no backseat | | Exterior Mods: | Fiberglass hood with cowl-induction scoop and glass decklid | | Safety Mods: | Rollcage, driveshaft loop, shoulder harness (current date), fire extinguisher, SFI-approved drivetrain parts | | Launch Technique: | 1,800 at line, then full throttle, shift at 5,000 rpm | | Best ET/MPH Prior to Event (1/4-mile): | 11.14 at 120 |

Owner Bio: Larry Snyder For many Pontiac fans, the decision to convert a hot street car to a dedicated racer is a tough one, and many opt to walk the fine line between street and strip. Lincolnton, North Carolina's Larry Snyder is not one of those people. After two years of street use, he took the racecar plunge with his '77 Firebird Formula and never looked back. The 38-year-old owner of Precision Automotive Specialists has been racing since he was 16. He purchased the Bird in 1990 from a co-worker and soon got to work. It was a solid but neglected example, and as such, was the perfect base to build a strong-running racecar. Going fast is all about power-to-weight, so in addition to a very potent 455 under the scooped hood, Larry put the Formula on a diet to drop the pounds. After all, a race-only machine can dispense with the creature comforts and take advantage of lightweight replacement body panels. Larry has done both and dropped close to 800 pounds out of his Firebird. It is now a svelte 3,225 pounds with him in it. Larry's friend Hank Skocz, shown with Larry, did the paint job. Snyder says his favorite times in the Formula are "every spring when I get behind the wheel and drop the hammer for the first time. Wheelstanders rule!" In addition to the racecar, Larry's current project is his Pro Street '68 Firebird. | Strip Specs | | Year/Model: | '77 Firebird Formula | | Race Weight: | 3,225 lbs | | Curb Weight: | 3,055 lbs | | Engine: | '72 YH-code 455 | | Cubic Inches Before/After Bore: | 455/470 | | Built By: | Larry Snyder | | Type of Fuel: | Sunoco 110 octane | | Carburetor: | Barry Grant 1,024-cfm Gold Claw, jets #86/#94 | | Spacer Plate: | Phenolic 1-in, four-hole, blended for improved flow | | Intake Manifold: | Edelbrock Victor | | Fuel System: | Mallory 250-gph electric pump, 1/2-in aluminum lines, and Mallory regulator set to 7 psi | | Heads: | '67 #670, ported | | Flow Numbers: | N/A | | Valves: | 2.11/1.77-in Ferrea stainless | | Pistons/Rings: | Ross forged 4.215-in/Sealed Power moly | | Rods: | Crower Sportsman forged, 6.625-in | | Compression Ratio: | 12.2:1 | | Crankshaft: | Stock nodular-iron 455, 4.21-in stroke | | Rotating Assembly Balanced: | Yes | | Camshaft: | Crane mechanical flat-tappet | | Camshaft Specs: | 260/268-deg dur. at 0.050, 0.583/0.603 lift | | Rocker Arms: | 1.65:1 Harland Sharp | | Camshaft LSA: | 108-deg | | Camshaft Centerline: | 105-deg | | Installed Position: | Straight up | | Ignition: | GM HEI, MSD 6AL and wires, ACCEL #134 plugs | | Total Timing: | 36-deg all in by 2,400 rpm | | Exhaust: | Hooker 2-in primary headers, 3.5-in collectors | | Power Adder: | None | | Transmission: | GM Turbo 400, performance rebuild, transbrake | | Converter: | TCI 9-in, 4,800-rpm stall, built by Gary Bruce at TCI | | Shifter: | B&M Quicksilver | | Rear: | GM 12-bolt, 4.10:1 gears, Strange 33-spline axles and spool, billet caps, C-clip eliminator, LPW Ultimate Series billet cover | | Brakes F/R: | Aerospace lightweight discs/stock 9.5-in drums (lightened) | | Wheels F/R: | Weld ProStars 15x3.5/15x10 | | Tires F/R: | Moroso 15x7.6/Hoosier 31x10.5x15 | | Tire Pressure: | 35 psi/9.5 psi | | Suspension Fr: | Moroso Trick Springs, Koni SPA-1 shocks, stock stabilizer bar removed, Wilwood rack-and-pinion steering | | Suspension Rr: | CalTrac bars, monoleaf springs, Koni SPA-1 shocks | | Chassis Mods: | Custom welded-in subframe connectors and eight-point rollcage | | Interior Mods: | Sweet Manufacturing steering column and quick-release steering wheel, aluminum door panels, Jaz Racing seats | | Exterior Mods: | Fiberglass hood with Pro-Stock scoop, lexan door windows with powder-coated frames, shaved door handles, and sideview mirrors | | Safety Mods: | Eight-point rollcage, driveshaft safety loop, five-way harness (current) SFI-approved drivetrain parts | | Paint: | Custom blue and silver | | Launch Technique: | Flash the torque converter to approximately 4,600 rpm as the transbrake releases | | Best ET/MPH Prior to Event (1/4-mile): | 10.13 at 129.9, Virginia Motorsports Park | | Best ET/MPH Prior to Event (1/8-mile): | 6.30 at 108, Savannah Dragway |

At The Track As mentioned before, Norwalk Raceway Park is blessed with a great surface and a competent staff who make the most of what is there. Of course, weather and the sun can cause trouble beyond what any mere mortal can control, and through no fault of NRP's staff, the starting line was getting slicker toward the end of the day. However, it's interesting to note that three of our four shootout participants made their best runs the last time out. The only one who didn't was running bias-ply street tires, per Pure Stock Musclecar Drags rules. This was in spite of the fact that the track conditions were eroding, and the air quality was slipping away. The reason for these late runs coming off so well for our quartet of racers was due to competent tuning and having settled into a comfortable and effective launch technique. We hear over and over at just about every one of our shootouts that making runs without the worry of surviving to the next round is key to allow for more tuning. After all, what we're doing with the shootouts is providing a relaxed test-and-tune session for racers to work out their combos. Dan Jensen Though his car was running well, Dan battled with traction all day. With nothing stickier than a set of reproduction Coker Firestone G70x14 tires, he posted his best e.t. and trap speed on Run 5: 12.55 at 109.58 mph. Except for one run where he blew the tires away, all of his passes were within 0.1 second and 1 mph, a very consistent showing. For a factory stock car to run that quickly on skinny tires was nothing short of amazing. His best 60-foot was a 1.88 (1.82 to date), quite remarkable considering the low-tech rubber. Deloris and Kevin Constant The Constants had a unique approach to their tuning. They did nothing to the engine at all--it was already dialed in. Tuning at the track was aimed toward getting the car optimized for the conditions at Norwalk that day. By stiffening up the suspension and keeping an eye on tire temperatures, they decided they couldn't improve on their initial pass settings and went back to that configuration. It rewarded them with the best pass of the day: 10.16 at 135.37 mph. Incidentally, the four passes they made were all within 0.06 second and 0.68 mph, which goes to show that when you have your combination sorted out, you're chasing after small improvements. In Deloris and Kevin's case, they found them. Lorin and Greg Budzinski With a fresh set of slicks under their '81 Grand Prix, traction wasn't much of a problem for the father-and-son team. After adding 2 degrees of timing and giving the 466-inch Pontiac a cooling-off period, Greg was able to shave off 0.09 second and add nearly 1.5 mph between his best and worst run. Their best run was 11.33 at 119.04 mph. Greg's 60-foots were very consistent, between 1.59 and 1.61 in five runs, and the Grand Prix lifted the front wheels about 6-7 inches every time. Larry Snyder Larry's Firebird was another case where a well scienced-out package was chasing after fairly small improvements. When the gains are that small, one is running at peak efficiency. The really big gains come from the correction of tuning errors. Snyder's game plan was to vary tire pressure and timing and also to alter launch rpm and shift points. After experimenting with launch rpm from 3,000 to 4,800, he came into his best combination, a 3,200 rpm launch, 6,200 rpm shift points, 9.5 psi in the slicks, and 32 degrees total timing above 5,000 rpm. The tuning and driving changes netted him a best of 10.20 at 129.87, a very respectable number that represents a lot of tuning and planning. The difference between the best and worst of his four runs was just 0.04 second and 0.8 mph. Even with tuning changes, Snyder's racecar was anvil-solid in its consistency. Conclusion Our four shootout participants this time out showed a great deal of skill and familiarity with their cars and equipment. They were able to optimize already well-tuned combinations to make the most of the available air and track bite. Next month, we'll be taking four more racers from our Norwalk shootout and presenting them to you for your evaluation and entertainment. Thanks to Bill Bader, Jr. from Norwalk Raceway Park, as well as Pete and Andrea Woodruff from Super Duty Promotions for making this shootout such a fun experience and a great kickoff for the Ames Performance Pontiac Nationals.
