Stick with the SB and look for a good block and buy a 383 stroker kit and then get a set of aluminum heads (if your not running in salt water). Talk with Bob Madera about the cam and get a Performer intake. You should easily be able to get 380hp out of it and save a bunch of weight by not putting the BB in. Also if you switch drives, the bravo is about 2" lower in the water which will add more drag.

Or you can bolt on a super charger and a good exhaust system and go play!

running in fresh water only...kind of a newbe but you can use a 350 truck block right? what is the difference between marine 350 and a truck 350? never relay knew if there was a difference or not? what marine parts do you have to use or can you use all truck parts?

Man , my first checkmate was an 88 enforcer but mine was the 330hp 454 and bravo1 , ran real good but was still just a 65 mile per hour boat , and you have to throttle past the chine walk to get that , i agree with building the small block you got , a few more ponies and loose some pounds and you'll see 70 alot cheaper then a BBC / bravo

as for the 2 bolt vs 4 bolt , if your not adding boost (blower or turbo) and your not spinning past 5k rpms i think 2 bolt main caps are fine

as for the alpha drive , SEI sells complete drives for 1400 bucks with a 3 year no fault warrenty , that means as long as you dont modify the drive they will replace it no matter whats in front of it

just my .02 , hope this helps

what kind of supercharger would you guys go with on a sbc? and what exhaust is recomended?

First off, is that 60 mph on a gps or 60mph on your speedo? Secondly the rest of these guys are right, build the small block. Had a buddy that went thru the hassle of switching from an alpha to a bravo and putting in a big block. He spent a solid week switching crap over and only gained 4mph. I'm currently building a small block for my boat and if you give me another week I will post some before and after results on how it runs. If you want pm and I can give you all the info I have on how mine should run.

60 on gps in the chop
