454 mag 1994 rebuild
 

looking for a good recipe for 500hp+ the motor is bored out to a 460 now looking for a good crank cam lifter intake and carb combo some specifics would be great.....

thanks

Your crank and rods are good, use a quality forged piston, marine gaskets, and contact RMBuilder here on the board for tha cam package and he will give you intake and carb specs.

The mags have a forged crank, but if you want more cubes use a 4.25" stroker crank with offset pistons. I made mine a 489 with .030 bore.
Like was said, RMbuilder is the best to use for your cam and matched components.
