It is not that much different to bolt up a big block. My question is what drive is on there now? Ifs its an Alpha, I would reconsider. Unless you are willing to go to a Bravo.

How much $$$ you gonna spend?
I bought a pair of re-man merc 383 MPI's with new bravo drives for just a little more than I had planned on spending on custom 383's alone, from Pro Tec Marine in AL
