Pontiac Pavement Pounders Shootout - Lone Star Edition, Part III
Owner: Travis Lochhead
Owner Bio
Travis Lochhead's mom purchased this T/A in 1977, and it's been in the family ever since. "Many lessons in hot rodding and in life have been learned in this T/A," says Travis, the 32-year-old oil field Service Supervisor. "It has been my favorite car and holds a special place in my collection." A cherished experience in the T/A was its first 11-second pass on motor. According to Lochhead, "On launch the passenger-side floor mat curled back and stood up for the duration of the run. I was dearly hopping to see an 11-anything on the timeslip, and sure enough it read 11.97." Travis would like to thank Pete McCarthy for help with head-porting and friends from Edmonton, Canada, Randy Rowlinson at Pro Stock Performance and Ian Thompson at Amazing Mechanical for their help with this T/A. | Strip Specs | | Year/Model: | '76 Trans Am | | Race Weight: | 4,005 lbs | | Curb Weight: | 3,785 lbs | | Fuel Level: | 1/2-Tank | | Type of Fuel: | 93-Octane Sinclair | | Engine: | '75 455 | | Cubic Inches Before/After: | 455/462 | | Built By: | Owner | | Carburetor: | 850-cfm Mighty Demon, #84/#93 jets | | Spacer Plate: | Moroso 1" plastic | | Intake Manifold: | Holley Street Dominator | | Fuel System: | Mallory 140 gph stock 3/8" line, Holley regulator set at 7 psi | | Heads: | 6X-4, ported, Ferrea 2.125/1.77 valves | | Flow Numbers: | 281-/210-cfm at 28" of water | | Pistons/Rings: | KB hypereutectic flat-top/Speed Pro moly | | Rods: | Eagle forged steel H-beam | | Compression Ratio: | 10:1 | | Crankshaft: | Nodular iron | | Rotating Assembly Balanced: | Yes | | Camshaft: | Comp Cams solid 252°/260° at .050, .600/.620 (with 1.65:1 rockers), 108° LSA | | Installed Position: | 4° Advanced | | Rocker Arms: | Harland Sharp, 1.65:1 roller | | Ignition: | HEI | | Total Timing: | 34* Locked | | Exhaust: | Hedman Husler Hedders 2" primaries, 3.5" collectors, 3.5" X-pipe, Ultra Flo Bullet mufflers, 3.5"-3" tails | | Power Adder: | Compucar and NOS nitrous | | Transmission: | Turbo 350, full manual valvebody | | Converter: | 10" TCS Street Fighter, 3,500 rpm stall | | Shifter: | Stock | | Rear: | Stock 10-bolt Posi, 3.73 gears | | Brakes F/R: | Stock 10.9" disc/9.5" drum | | Wheels F/R: | Weld Draglite 15x7/15x10 | | Tires F/R: | BFG 225/70-15 / M/T ET Street 28x12.5x15 | | Tire Pressure F/R: | 30 psi/13 psi | | Suspension Fr: | Stock, stabilizer bar removed, factory shocks | | Suspension Rr: | Stock, stabilizer bar removed, CalTrac bars, factory shocks | | Chassis Mods: | 4-point roll cage | | Interior Mods: | Auto Meter fuel pressure gauge | | Exterior Mods: | Aftermarket hood scoop of unknown origin | | Safety Mods: | Driveshaft loop, SFI-approved drivetrain parts, 5-point harness, aforementioned roll cage | | Paint: | Silver | | Launch Technique: | Load to 1,500 rpm and go! | | Best E.T., MPH Prior to Event: | 11.66 at 117.35 |
