Bravo drive? I'd say up to 500hp if so. Should be a fun time like that. 
That is what I am afraid of. I have a set of Dart II Merlin heads I am building for this motor because the core I bought had an eroded exhaust port on one head. I was also going to convert to a roller cam for about 5400 rpm. But if it is too much, I will just put a hydraulic cam back in it. So what hp level should I build to for this boat? It weighs 4000 lbs. and has a Bravo I.just me p22 said:A stock 454 will push your 220 to it's limits.
Very true, I would hate to build it and want more afterward. I can build a solid, reliable 450 hp engine within my budget. So I think that will be my plan. I just saw my boat is not exactly like a lot of the boats on here, and thought there may be a reason. But no one has really expressed too much concern, so 450 it is.Super24 said:Well, you don't hear people say "I have TOO MUCH power" very often.
