safly I'd say 427, but I know a guy building 500+ aluminum ls1 with deck plates, long sleeve stroker, sheet metal intake and twin 90mm TBs.......how much money do you to spend?

[sirzones]

have not thought about cost yet,I know forged bottom end will be a must.
looking to build 700 to 800 hp for a mud rail car. uit should be under 1900lbs
when finished.
