thats still pretty vague... a totally indestructible bottom end will run u upwards of 6,000. lol
How high u rev the motor is gonna be dependent on the heads/cam setup you run... psi doesn't have anything to do with it
if your not taking the car over 6500-7000 rpms I'd probably just recommend some eagle h-beam rods and a scat steel crank
if u plan on spending a lot of money on a really good set of heads and put an aggressive cam in the car (making power to like 8000+) i'd upgrade to the superlight steel crank and a set of oliver billit rods
all how much money u wanna spend and what power numbers ur tryin to reach... its really hard to plan a bottom end without knowing what u plan on doing to the top half of the motor
