1971 Chevrolet Camaro - The Other Camaro

Countdown to 8sOne guy's approach to horsepower, traction, and the quest for a lower e.t.

Troy's starting-line video shows how the aluminum T/A rear cover disappears when both axletubes, which had been fully welded into the centersection, broke, snapping the driveshaft and shoving the pinion snout (still connected to the rearend) through the floor and ripping the backseat upholstery. That's when you know you're hooked up. All of these compromises are in an effort to keep this a streetable car. The torque converter, leaf springs, and pump-gas-friendly compression limit the car's ultimate dragstrip e.t. and speed but pay off in terms of fun-behind-the-wheel time. We went for a check-out ride with Troy, and when you've got a 9-second car that will idle in neutral at 1,000 rpm with an idle vacuum of 9.5 inches even with a monster 256 at 0.050 camshaft, that's not much of a compromise. Even Troy was shocked when he measured it. The ride is almost living-room comfortable, but understand that's with soft shocks, no front sway bar, and not-for-highway-use slicks at 20 psi--certainly deceiving for a pavement pounder. The converter is tight, in fact it pulls at part-throttle almost like a stock converter.

Still, the lure is there to run an 8 in full street trim except for the slicks. Troy believes it can happen, and that's half the battle.
