454 330 turning into 496 stroker questions
I have a stock 454 330 that is tired and wore out.
So I'm Turing it into a 496 bbc 60 over on the block Forged crank Manley h-beam rods Crane gold rockers Sumit racing oval port heads What is recommended for Intake and carborater I have an edlebrock 750 but won't be enough I don't think. Just looking for Pistions Valves Intake Carb cam and i need some ideas Any suggestions and thought please and thanks Any thought on setup would also be help full It's going in a 24 predator marine viper 4000lbs With imco ext. box with dual hydrolic steering Bravo 2 upper with brave 1 lower |
I would put in a roller cam. RMbuilder on this site can get you the right cam. You shuld be able to pull 525=550 hp no prob. The intake that come with the Merc HP 500 is a good manifold and and with a 850 cfm carb you should be fine. BTW make sure you check the block for clearances on the rod journals.
Good luck with the build. Wannabe |

you really dont need to go .060 over, a 489 will make as much power and the 496....just stay away from pro comp heads....

I have a bob m cam w a .6 lift used but for 1 season pm if you want to talk

Whats wrong with the Pro Comp Heads?
|
I'm not using pro comps, but have a few friends who use them (auto application) with good results. They buy bare casting and build the heads. One guy runs low 8's with them. They make good power and are dirt cheap. Think he gets them for 300 a cylinder bare casting. It sure is temping to throw a set on ad do away with my 088's.

Your going to have a hell of a lot of money in that thing before your done. Only thing you'll be using is the block and it's probably a 2 bolt. Lot cheaper ways to go about this.

Your valvetrain alone roller cam, lifters, pushrods, roller rockers, springs, retainers, severe duty intake valves, extreme duty inconel exhaust valves is going to set you back over 2K EASY. Your still going to need the forged crank, manley rods, forged pistons, pair of heads, timing set, intake, carb, fuel pump, oil pan, valve covers, flame arrester, gaskets,machine shop work |
