(Cam) How big can you go with Dart pro 1's Ive done a search but couldnt find any info, i have a buddy with a 2002 Z-06 Vette and hes running Dart heads with a comp XER 232/234 598/595 112 lsa cam. He wants it to hit harder so hes been looking into swapping in a bigger cam but he told me that Xtreme Horsepower told him he cant go much bigger. He would like to run the Raptor cam or ms4, Do you guys know if his piston to valve clearance would be ok running any of these cams? He's currently laying down 443 RWHP with this combo, so how much of a gain do yall think he'd pick up going with a bigger cam swap ? Thanks

I'm guessing he has Dart 205's and I would estimate he is close as is. Going any larger would most likely warrant flycutting.
I'm running Dart 225's with a Vinci 222/228 .585 on 115 with 1.8 Crane rockers and had to fly cut .040" on the intake. The exhaust had exactly .100" clearance. I measured PTV clearance with a dial indicator and degree wheel.
