4.3 Marine Eng To A 350 Chev Eng

I Am Looking At What It Takes To Swap A 4.3 Marine Eng To A 350. I've Been Told It Is Simple, But I Need To Know What It Will Take In Parts.

Depends on clearance in front of engine. Most boats have room. The next thing is the exhaust manifolds and the intake/carb. Boat exhaust manifolds get real spendy quickly.. Carbed or injected 4.3? Mechanical fuel pump? One piece 350 V-8 uses same flywheel as 4.3.. Some places will require re-certification of boat..
