I cant believe this motor...guess I can blow more $$ and buy atomic adjustable cam gears.If I was to do this again Id be buying the largest undersized rod bearings and give it a slight stroke or buy flat tops with just 5cc eye brows cut on all 4s. I don't even know why they put valve reliefs on the exhaust side when its the intake that has clearance issues.Im guessing my timing cover case aint going to fit either now??

Even if I ran a 0.650" lift cam on the exhaust side she still wont require those valve reliefs. Ex is purplethat's measured @ standard lift on a standard cam .015 deck clearance .015" service limit left on head .012" head gasket roughly 9.3:1 comp ratioIts no problem this happens to a lot of built engines. Just needs valve reliefs cut on the CORRECT side. Cams are being adjust via Delrin on the tension side of the cam. Link to comment Share on other sites More sharing options...
