Y not just use a 4 cylinder?

Woops, sorry I misread your post. I looked past "stroke longer than 4.250"
My apologies

Mild, I'm going to have to spec a 3/4 race cam for that build.
Just my professional opinion...

You guys think 3/4 will give me enough low end ? I want max power between 1200-2400rpm. Don't forget this is a true marine offshore engine

This wouldn't be quite so funny if it weren't completely true! Just wait, a post will pop up in a couple weeks and many aspects outlined above will be utilized. Classic

Can I put a ProCharger on my 3.0L? If so, should I step up to a Gen II Alpha or will the Gen I be fine?
