I am looking for a roller camshaft lift/duration spec that the 350 5.7L vortec marine engines used stock ( carburated). I am building a new engine to match the other one that didn't blow up!

197/207 .430/.450 109 LSA = Roller Cam

200/212 .400/.410 110 LSA = Flat Tappet

Thanks! found GM part# 14097395 appears they use this cam in the marine 350's and the ram jet 350 uses the same cam :shocked:

Yup. They can be found on eBay VERY cheap.
