I found the article that I was refering to.... It's from Super Street Cars Feb '71. At 1st the bone stock LS-6 owned then by Eddie Fitzpatrick, showed 220 hp at 4800 rpm at the rear wheels and 460 lbs of tq. After removing the smog equipment,installing headers, aftermarket intake, 850 dbl pumper with carb spacer, .080 jets all of the way around,ACR43T plugs gapped at .035 and a distributor curve the engine showed 310 rear wheel power and 700 ft lbs of tq at an engine speed of 6000 rpm.They then put in .082 jets all of the way around and got 350 hp and 720 ft lbs of tq.Lastly they closed the headers and put on the air cleaner and got 290 hp and 670 ft lbs of tq!!! With 7" slicks and open headers it ran a 12.51 at 111 mph. ALSO, concerning the dyno test in muscle car review,they had headers on that mill and had to play with the timing a lot and it had an after market cam to get the numbers that they got.Expecting 450 plus hp out of a STOCK ls-6 is wishful thinking.Dont get me wrong, I'm not knocking the ls6, I have 1, but the hype about their power, amongst other things, has caused part prices to balloon out of this world!!!
