use your ls block with a gsr crank and custom rods for a slightly better rod/stroke ratio. also, use 15:1 pistons and a 1 layer headgasket and 20 psi low setting/30 psi high setting with some jet fuel and octane booster and water injection.
youre gonna spend a fortune building a custom engine for boost, so you might as well do it right.
