Owner Bio: Bill Baker
Fullerton, California, resident Bill Baker has been a GTO fan since he was a mechanic in Lake Tahoe back in the '70s. He got the chance to drive one and, even at 6,200 feet above sea level, the car was fast. "I ended up buying that GTO," he says, "and have owned three others and a Firebird, all '69s." The 50-year-old has been racing for five years and lists his most memorable moment in his GTO as the time he was, "showing off and had a axle shear at the bearing, launching the car airborne, skidding to a stop, and watching the tire heading down the street. All this with a crew of city workers watching." His advice today? "Use steel axles!" | Strip Specs | | Year/Model: | '69 GTO | | Race Weight: | 3,750 lbs | | Curb Weight: | 4,050 lbs | | Engine: | '70 XF | | Cubic Inches Before/After Bore: | 455/468 | | Compression Ratio: | 9.2:1 | | Built By: | Owner | | Fuel Used: | 91-octane unleaded | | Carburetor: | Rochester Quadrajet, factory jetting | | Spacer Plate: | 1-in wood | | Intake Manifold: | Edelbrock Performer RPM | | Fuel System: | Mallory 140 pump, Mallory fuel-pressure regulator and 5/8-in lines | | Heads: | '76 6X-8 | | Head Porting: | By SD Performance to flow 265 cfm intake at 0.550-in lift | | Valves: | 2.11/1.77 Ferrea stainless | | Pistons: | KB hypereutectic flat-top, 4.21-in bore | | Piston Rings: | Total Seal Moly top, cast-iron second, file-fit | | Rods: | Stock cast No. 541000, ARP rod bolts | | Crankshaft: | Stock GM nodular iron, 4.21-in stroke | | Rotating Assembly Balanced: | Yes | | Camshaft: | Crower flat-tapped mechanical, 240/248-deg duration at 0.050, 0.477/0.501 lift with 1.65:1 Comp Cams roller rockers, 112-deg LSA, 108-deg lobe centerlines | | Installed Position: | 6-deg advanced | | Distributor: | GM HEI with Jacobs Fire Control | | RPM When Total Timing Is Achieved: | 32 deg at 3,000 | | Exhaust: | Hooker Super Comp headers, 1.75-in primaries, 3-in collectors, SpinTech X-pipe, 2.5-in mufflers | | Power Adder: | None | | Transmission: | Turbo 400 automatic, governor set to shift at 5,000 rpm | | Converter: | Pontiac Special 10-in, 2,800 stall | | Shifter: | Stock GTO | | Rear: | Stock GM 10-bolt, 3.55 gears, Auburn posi, steel axles | | Brakes Front: | GM discs 10.9-in | | Brakes Rear: | GM drums 9.5-in | | Wheels/Tires Front: | 15x7-in Rally IIs / BFG T/As 245/60R-15 | | Wheels/Tires Rear: | Custom 15x9-in Rally IIs / Hoosier QuickTime 28x11.5x15 | | Tire Pressure Front/Rear: | 32 psi/15 psi | | Suspension Front: | Stock springs, factory 1-in swaybar, Edelbrock IA shocks | | Suspension Rear: | Stock, boxed lower control arms, polyurethane bushings, airbags, 1-in rear swaybar | | Chassis Modifications: | None | | Interior Modifications: | None | | Exterior Modifications: | None | | Safety Modifications: | Driveshaft safety loop | | Launch Technique: | Footbrake launch at 1,000 rpm | | Best ET/MPH Prior to Event (1/4-Mile): | 12.93 at 105 |
