I built my 350 SBC T bucket motor. with roller tip rockers, screw in studs, bronze valve guides. Hot hyd cam, and lifters (I forget the numbers) I am running a TH350 so the cam can't be too wild, new valve springs. dual 4 barrel carbs. bottom end bluprinted. It all has to work together. probably too much carb but 2 4's and an old school crab top mallory dual point distributor look cool.
