Re: 2001 Pure Stock Drags
Rob & Pete,
Rob, that's the article... As mentioned, not a lot of info on the stock setup, but interesting all the same. The following information was taken from the article and posted a while back (by Joe perhaps?).
First off, the engine tested was supplied by Bill Porterfield, who at the time of the test, owned ZL-1s #1 and #3... Anyway, Bill supplied all the NOS parts, and tried to simulate the tests done in '68. So, here are the results:
TEST 1: All accessories, production exhaust manifolds and Camaro chambered exhaust system; 36 degrees of timing; rev limiter set at 6750. Result: 375.7hp@6500 and 358.5lb-ft@4500
TEST 2: Exhaust manifolds were replaced with 2 1/8 inch headers. Result: 418.9@6500 and 404.4lb-ft@4000
TEST 3: The air cleaner, alternator and A.I.R. pump were removed. Result: 447.2hp@6500 and 408.0lb-ft@4000
TEST 4: The Holley carb was rejetted for a richer mixture, and the timing was set at 39 degrees. Result: 444.2hp@6500 and 410.7lb-ft@4000
TEST 5: The chambered exhaust system was removed. Result: 523.6hp@6500 and 469.7lb-ft@5000
Pete, I'll see if I can locate the actual issue tonight when I hunt for the camshaft information.
Regards,
Stan
