Ratman- nice sounding package.... the cast iron 882 large chamber head is a stock GM piece....... do you know what they came stock in???.....Ive got twin 89 350 mags 270hp(carb) in mine, all stock now, runs about 64-65 now................Id like to see about 400- 425hp/side to wake the thing up a bit.......but not break the bank either.........doug

Re: smallblock re-power

pull my trigger, the 882's were very common heads during the gm low compression years. id call some cyl rebuilders and you can probably scrounge up 2 sets easy enough and cheap enough. they come with 1.94 in i spent the cash to install 2.02 but it isnt neede for marine and 6k redline. there is a place in ft laud engine builders warehouse where i got the scat cranks for under 200 bucks is a cast steel 5140 crank and i wrung it out to 7500 all day long no problem just be sure th balance your rotating assm. ths 5.7 gives it a decent rod ratio but i think there is a place selling 6.0 ford rods resized for sbc for very little money for an even better rod ratio., doug herberts roller cams are inexspensive as were his springs and roller lifters. the trw forged flat tops through summit racing were cheap by piston standards. it idled like nice and low and made unreal torque from idle to redline. you'll love the power. ratman

I contacted them and they said they don't make marine applications. I guess you could buy a short block and built it from there. I'd love to upgrade to 427 or 454 smalls.

Stock 350's (5.7's) with Alpha's. They are pretty freshly rebuilt but would like more power. I'm a hot rod guy so I can build the motors but of course, marine stuff is a bit different than automotive. I'm thinking about using the World Castings short blocks and working my heads. Need to do plenty of research: cam, head compatability, carbs/injection etc. Anybody have any idea if this would work?
