Bigger cam qeustion
Bigger cam qeustion Ok, I had a Comp Cams 236/236 585/585@112LSA. I had a lifter crap out and destroyed the cam. So I called Comp Cams and told them i was going bigger and they recommend the 281/289 617/624@113LSA. I talked to a guy yesterday that said that I need to "Fly Cut my pistons" in order for the cam to work. I was wondering how true this is. If so/not, what all do i need to do in order to run a cam like that with a stock bottom end and stock valves?
thats prob @.006 so it should be a 231/239 @.050 that would be a good cam.
out of all the cams i have ran on my 346 the best all around cam was a xer 281 232/234 .587/.589 on a 112+2 had explosive mid range but still pulled past 6500

Yea if you called Comp they recommended a cam at advertised duration (at .006").Thats a bigger number than at .050".Like quick346 said-looks like Comps lsr lobes 231/239.That should be a good cam.

the answer to your question is NO BODY KNOWS unless they degreed THAT cam in YOUR engine and checked PISTON TO VALVE CLEARANCE. do yourself a favor and check ptv clearance no matter what anyone tells you. if its gonna be close, it NEEDS to be checked. period
