I'm looking to swap out the carbed marine power 454 in my 2000 21' ultra in the next couple of years. The 454 has been solid, it's a 55 mph boat with it. I was curious what route to take for a swap and rerig. Would it be best to use another big block - bigger hp and pump work, or something like a new LSA 6.2 and dialing it all in?
