TJ, there is no way you would want to use a stock crank. Stock length, sure, but go with a wiseco or hotrods crank and rod. That much motor deserves the best bottom end you can put under it.
my last bump then ill let this thread die just wondering bout the carb and if i could use my exhaust as that would save me a lot of money i know i might lose a couple peak hp for not using there exhaust but $$$$$
