h2b ls swaps dont stand a chance.....hitme up if u need some proof...i got h2b n i got everyone wantin to do it...but since u ls might as well start a turbo build..ls drag motors are not dailys.ctr pistons in ls will raISE THE COMPRESSION LIKE CRAZYYY u will be fast once tuned but i dont think you will be able to drive around like that.. every motor is capable of being fast but reliability is a different thing.
