dyno numbers!
Well I made it to east texas muscle cars to get a baseline on my setup yest. eve. And by the way Stephen and the guys over there are real nice guys and have a great knowledge of these cars.. ok so to the Dyno results. The first pull only showed 484/414. So we knew something was wrong for the tq numbers to be so low so we started looking at things and stephen found that the pos vararam lid had collapsed and was just dangling there. So we put it back in and tightened as well as we could and made another pull. This time it made 495/450! And this was with a 12.1 a/f ratio. So its got some left with leaning it some. Not too bad I guess. What do y'all think

Stephen@ETMC is awesome. With some fine tuning I'm sure you'll hit 500rwhp

That cam looks like a winner.
With .65x and .64x lift, I'll guess the intake lobe is a 235 lsk WITH A .646" lift making it a 4 degree or less, split. Nothing under 235 duration has a lift over .63x. Assuming a 239 exhaust puts overlap at about 11 degrees. Its a pretty agressive cam and looks interesting.
Can you post the dyno sheet?
