    call your favorite cam manufacturer and give them the specs of your car. weight, operating range, streetability desired, transmission you're running, engine specs, etc. sounds like with your build u need a custom. good luck!

    Will a 4.25 stroke crank clear a LS1 block? Who makes an off the shelf 4.25 LS1 rotating assembly? You're going to need some seriously short skirt pistons (custom) to keep them in the bore. The piston slap/cylinder wear with the short skirts + long stroke is going to be a problem. Would a 402 LS2 be cheaper and more reliable (considering the sale of the LS1)?

    Just an opinion.

    I've heard of getting a lot more wear and less reliability with the 4.125 cranks over the 4"....just seems like once you go past 4" its a lot more work...unless you go with a tall deck
