Engine swap

Hey All, Let me start by saying my 91 auto is running fine. Just have seen alot of engine w/trans and ecm's on e-bay and was wondering if a complete LT1 or LS1 would fit into the 91? Thanks-Doug:dance

Haven't seen the LS1 swap yet, but there's no reason for the LT-1 not to fit. It's the same block as the L-98, and every other Chevy small block for that matter. It's only the top of the engine that has major differences from the earlier blocks, such as reversed water flow.
