Default 600 ci NA build

I see it seems like a lot of people on here are in the process of building or have built bigger CI NA combos. We are in the process as well of building 2 600 ci NA combos for our boat. Just curious of what a lot of guys combos are and what kind of power they made.

They will be 4.605 bore and 4.500 stroke. For those short blast we will turn it up to 7400 ish. We have a 32ft Skater so it accelerates extremely well.
