So, if I ever got around to it, I'd pick up an LS1, and this is what I'd do:

Goal: 7500rpm twin turbo LS1 monster

balanced, blueprinted block
forged crank, pistons, rods
all new valvetrain
cams (not sure which yet, of course.)
dry sump oil system
Twin GT30R turbos
dual 3" exhaust
big ole fmic.

suggestions?

btw..........I'd prefer to drop it in a classic chevy chassis. late 60s chevelle or malibu chassis maybe? With a T56 tranny possibly....
