Building a marine engine

Building a marine engine

Building a marine engine

(OP)
I am building a fresh water marine engine and am looking for some pointers. It is a small block chevy 350 standard bore and stroke, Flat top pistons, Dart II heads 64cc 202 valves. I was looking at an Isky cam with 221/232 degrees at .050 and .465/.485 lift or one from Keith Eickert with a 218/224 at .050 and a .495/.503 lift. It has a 4" through hull exhaust. Also any ideas on intake manifolds? I was looking at the dart but it is a single plane.

RE: Building a marine engine

I like the OEM LTI manifold with a list 3310 Holley for speed boat engines where good idle, mid range and good fuel economy are required with reasonable top end.

Regards
