the rotating assembly are a good start or you can do it like this
FORGED 3.750 stroke crank for a 350 a good block bored .30 over and notched for clearance, forged 6.0 rod, some high dome pistons, aluminum heads (everyone i talk to THAT RUNS PROCOMP says procopm is good for the money) and a good cam to fit the build. thats how i would do it
JMO id go with forged crank and rods if you can afford them just for extra insurance but the scat 9000 crank is a good cast crank from what i hear
