    Billet Main Caps

    Are the Katech Billet Mains worth the price? I am building a 500rwhp ls6 and was wondering for my application if they would be worth the price? I plan on doing lots of RR and some drag racing.

    The stock bottom end of an LS6 is plenty strong and will support 500hp. It's your money and a little extra insurance never hurts. I say go ahead and spend the extra dollars, why not since it's your money.

    I am just trying to figure out if it is worth spend $400 on those. I may get all the other parts and see what it adds up to and if I have anything left over with my budget I will then buy them.

    You'll be fine with stock mains, but I would get ARP hardware for both the rod bolts and main bolts.
