Pontiac Pavement Pounders Shootout SoCal Edition, Part III
Owner Bio: Jim "Old Man" Taylor
In order to prevent him from being confused with HPP's tech contributor who has the same name, this Pontiac racer goes by Old Man Taylor, or OMT for short. Jim hails from Escondido, California, and has been racing on and off for over 40 years. He still owns the '64 GTO that he took delivery of on March 28 of the same year. The 64-year-old grandfather of four built this Tempest in order to keep from breaking parts on his GTO. "The Tempest is special to me because my wife provided me with the up-front money to buy the project car," Jim says. "She was not particularly interested in cars but shared in my enjoyment. She passed away on January 6, 2004. We had been married almost 40 years." Thus far, Jim's favorite moments in his Tempest were winning the Pro-Bracket class in the '04 Pontiac Drag Days eight-race series; his first event win at the March, 2001, PDD race; and the first time racing the Tempest after eight years of part-time construction. In addition to the Tempest and GTO, Jim also owned a '69 Catalina wagon with a Tri-Power-equipped 428, and a gold '78 Special Edition four-speed Trans Am. | Strip Specs | | Year/Model: | '64 Tempest | | Race Weight: | 3,440 lbs | | Curb Weight: | 3,240 lbs | | Engine: | '68 XS-code 400 | | Cubic Inches Before/After Bore: | 400/412 | | Compression Ratio: | 9.9:1 | | Built By: | OMT | | Fuel: | Chevron 91-octane | | Carburetor: | Holley 9375, 1,050 cfm | | Jets: | No. 87/No. 87 | | Spacer Plate: | 1 in | | Intake Manifold: | Edelbrock Victor | | Fuel System: | Aeromotive 350 gph pump and fuel pressure regulator, AN No. 12 primary line, No. 10 return line | | Heads: | Edelbrock aluminum | | Head Porting: | Butler Performance, flow 318/261 cfm | | Valves: | Manley stainless 2.12/1.66-in | | Pistons: | Ross forged, 4.18-in bore | | Rings: | Childs & Albert ZG | | Rods: | Crower forged steel, stock length | | Crankshaft: | Factory 3.75-in stroke | | Rotating Assembly Balanced: | Yes | | Camshaft: | Ultradyne mechanical roller, 271/278-deg duration at 0.050, 0.626-in lift with 1.5:1 Crane roller rockers, 106-deg LSA | | Installed Position: | 4 deg advanced | | Ignition: | MSD electronic | | Total Timing: | Locked at 35 deg | | Exhaust: | Doug's Headers, 1.875-in primaries, 4-in collectors, 3.5-in crossover, 4-in Racemaster mufflers | | Power Adder: | None | | Converter: | TCI 9-in, 4,200 stall | | Transmission: | Turbo 400, shift kit, transbrake | | Shifter: | B&M ratchet | | Rear: | GM 12-bolt, 4.56:1 gears, spool | | Brakes Front: | GM 10.9-in discs from a '70 GTO | | Brakes Rear: | Stock 9.5-in, aluminum drums added | | Wheels/Tires Front: | Monocoque 15x3.5-in / Mickey Thompson 27.5x4.5x15-in | | Wheels/Tires Rear: | Monocoque 15x10-in / Goodyear slicks 29x11x15-in | | Tire Pressure Front/Rear: | 34 psi / 10 psi | | Suspension Front: | Moroso springs, Koni race shocks, tubular upper control arms with limiters, front sway bar removed | | Suspension Rear: | Custom antiroll bar, Gazan adjustable upper control arms, stock springs with one coil removed, airbags with 20 psi in each | | Chassis Modifications: | 12-point rollcage by Race Cars & Stuff, rear frame channeled for wider tires, mini-tubs, trunk-mounted battery, fuel cell | | Interior Modifications: | Single JAZ seat, custom shifter platform and pedestal for delay box and transbrake button, aluminum door panels, custom instrument panel, rollbar-mounted switches | | Exterior Modifications: | VFN fiberglass hood (with hoodscoop), front and rear bumpers, custom paint and graphics | | Safety Modifications: | 12-point cage, driveshaft safety loop, five-point Peak harness, SFI-approved drivetrain parts | | Computer Programming: | None | | Launch Technique: | Transbrake at 4,000 rpm, just below 4,200 stall | | Best ET/MPH Prior to Event (1/4 Mile): | 10.71 at 124.15 | | Best ET/MPH Prior to Event (1/8 Mile): | 6.77 at 101.13 |
