Supercharging a 351 Engine

there are other ways to get the supercharger to work it's just not a bolt on thing and not that hard to make it work right with the reverse rotation engine and right type of supercharger. All it requires is a custom made mounting bracket and an extra idler pulley. Pretty simply stuff if you have access to the tools and the know how to use them.

vortech makes a nice accessory mount supercharger, it mounts like a altenator, it is a sweet set-up.
   personally one of these days im going to put together a turbocharged engine, you can by set-ups pretty cheap from e-bay. I have a friend installing one on a LS1 he bought the turbo for $650.00 and bought what is called a box of pipes to manufacture the exhaust, i think the biggest problem in a ski boat would be the lag on holeshot, i know i can build a trans good to 800 hp so that wont be a problem. i do have a good 5.7 set aside for this.     one of these days.......

the boat above appears to have a spyder tower, so it would probably be an 02-03?

no they run the same temp unless you have turbos then you don't want them covered at all.

   What you need is a ba$$ boat

What you need is the Viper 8.3L V10, 625 HP, 600 ft*lbs torque by Ilmor Marine.
I read an article a while back in Boating Magazine about a boat with two of the 550 HP versions in it. The boat raced a Viper sports car from Miami Beach to Key West. Guess who won Guess who had more fun

Oh crap!! That's nuts. Maybe I can use a shoe horn to get it in my boat. Does ACME make a five blade prop?

eric says he can get one to handle 800hp, the base unit can handle up to 400 hp with out an issue, the hp not the issue torque is and I've got about 390 ft lbs of torwue on mine and haven't had any issues in stock trim but everthing was new when I did the engine.

Thanks eric. I'm planing to do a couple of upgrades to the engine this winter. I'll probablly wait until the next time I break a reverse plate, then go through the tranny and beef it up.

jimbo, you must have a AS1-71C with one reverse, i probably have a spare case that I'll give you that will except the 2 reverse plates and with the reverse plates i use you will never snap a reverse plate again, let me know when your ready. the best transmissions to use are the 10-17-003 or 004. keep your eye open for a cheap core and use yours for a spare

79nautique you thinking of trying for a reverse rotation balanced stroker?

79 the biggest problem now is finding the rev, rotation 1 piece il seal,PCM no longer is making it, with the resources you have 79 i know you can find a supplier.i bought the last one PCM had,thanx Vince,Skidm,you the man.79 wish you could take a ride , you would have to do it to yours,well worth all the headaches..... boat dr

Cape cod dont have the room under the box,'64 american skier. low tech look for a high tech motor,how bout it 79 cuold we trick that one out,twin turbo's spooled up at 5500 with 3" striaghts,= the big O........ boat dr

Yes, There was one on ebay about 3weeks ago. Think it sold for about $7000. Twin turbo with jet drive.

Well, well, well...this just in... a guy I know has a Chevy 350 engine from a van that he'll give me. All I need to do is pick it up. I'm thinking I'll tear it down and rebuild it as a 383 Stroker, upgrade some parts to marine grade (carb, starter, altenator)and put a cooling and exhaust system on it. Hmmm... put a LH prop on it and put my St Pauli Girl looking German wife in the observer seat for ballast and not worry about the rotation. Hmmm Seriously thinking about this for a long term project. This way I'll have an engine ready to go when the 351w throws craps.
