Pontiac Pavement Pounders Shootout - Norwalk Raceway Park Part 1
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.
