Re: 1979 305 chevy rebuild or replace?
I'd recommend that you custom build a 5.7L and get away from the fully dished pistons.
Start with an automotive core that has NOT been raw water cooled.
With the correct Q/E (quench effect) piston (for the cylinder head chamber size), you'll still have the desireable Marine C/R!
Any good machine shop staff can help you with your selections.
Cost increase is minimal, and you'll end up with a better suited Marine SBC.
