It's getting to where you can't talk to anyone who hasn't experienced a cam failure. I keep hearing more and more stories about cams failing and I can't help but wonder if some of this max lift theory isn't responsible. To my way of thinking, there has to be a mechanical limit there somewhere and I'm thinkin' that there will be some pretty horrific pressures encountered between the lifter face and the cam lobe, possibly enough pressure to wipe off the lube and allow metal to metal contact. Yeah, this reminds me of the "extreme energy" cams where they maximize the lift for each degree of cam rotation. "they seem to have less duration that comp cams but higher lift." If I simply switch the heads to the older 64cc heads, run a thin steel shim gasket to make some compression with my dish pistons, and use the cam you suggested, with a performer intake and a good carb, either my Q-jet which needs rebuilt correctly, or maybe an edelbrock, do you think I will have a noticable increase in power? Not only did I not want to overcam, I didn't want to under cam. I guess I was tring to get the biggest cam possible for my situation. Sounded really cool at the lite, but a pinto with a miss had me in the 1/8 mile.ha ha. I did that 15 years ago with my first hot rod. I agree that if you over cam, you will have the problem you mentioned. If you look at my other post, I put some specs there for reference. I noticed that they seem to have less duration that comp cams but higher lift. That is why I was looking at the voodoo cams. I understand that the more duration you have, The higher up the power band you go.
