Hey Guys,

I'm looking to replace my cracked 1985 305 merc 230hp engine. Few questions.

Q# 1 - I can replace w / standard 305 (flat Tap) with a 305 w / heads that has roller cam & lifters. HP difference?

Q# 2 - 350 flat tap (260hp) vs 350 w / heads that has roller cam & lifters.. HP difference?

Q # 3 - Can my 305 carb fit on the 350 merc without having to be re-jetted??

Thanks!
