that motor stock put out about 190 rwhp i call bullshit on 11 psi

the esteemed reverernd cooper gets it right.

Everything "stock" (ie heads, cam, intake) with a little allowance for a better exhaust, I wouldn't expect more than high 300's @ 11 psi....though there are those that disagree, it's true...you roughly double hp/tq for every 14.7psi, so were he truly "stock" even 15 psi wouldn't get the numbers he claims.

Im actually going to agree.

Few things... First off the stock valvetrain wont support 496/567. He would have to spin high and valve float would accure, unless he hit 496 at 5800 which I dout on a stock top/bottom end. Also lets not forget thats a stock block lol Ive split a valley at 450 to the tire, but that was spray totaly different situation. Put back the 15% lose and thats a 570/652 at the crank...lol Im gonna call BS as well.... But bang for the buck thats a nice kit.
