Yea thats what I figured, the machine shop guy stopped by and it turned out it was because it was a factory roller block, and I was using a flat tappet setup with a double roller timing chain and gears. He showed me where it needed to be grinded, which was a whole lot, so we opted to get a truck timing chain and gears instead. As far as the rods and cam problem, I have been hearing that 60 thousanths is the recomended clearance between them, Im barely hitting, and only in 2 cyclinders that I know of as of now. I guess we will see how tha goes, I thought about a small base circle cam, and to be honest I am a little unsure of how the exactly are designed. How much more clearance will I get? And will that mean I need a special pushrod? Thanks for all the input, this seems to be a really active forum, prolly the most active I've been on, very helpful, thankyou.
