Small Block Cam question
 

Helping a friend put a new motor in my old boat.
He bought a GM crate engine rated at 330 hp w/ 9:1 comp.

The cam in it is 435/460 lift
212/222 duration at 50
LC are 109* atdc/ 116* btdc ex.

Is he gonna suck water in this SBC?
Thanks
Mark

Also he has stock type/aftermarket exhaust thru the hull. He needs to improve on that in the future but... it's his first boat.
Thanks

anyone? please

It's the 330hp vortec crate engine.

Many are running around with this and not having issues. Pretty mild cam.

I don't remember if the crate engine uses stainless headgaskets and brass freeze plugs. I would find out and make necessary changes if needed.

It has brass freeze plugs for sure. Is stainless head gaskets needed for a fresh water only boat?
Thanks for the reply!
