Re: LT-1 Torque Info
Straight from the factories, most cars were not all that impressive. With emission controls, the engines came with very lean primary jetting, and a very slow advance curve that might be all in by 5K rpm. To get the numbers that GM put out, the engine was probably on an engine dyno with dyno headers and tuned for performance. I have a magazine road test of a '70 L34 Chevelle that turned a best of 15.1 seconds in the quarter. Hardly 350 hp working there. L88 engines at 430 hp might have actually been not all that far off as the engine came installed in the Vette. Tune it and give it open headers and the difference was huge. The quarter mile is the only true power test.
