I have a 92 Indy 500 efi that I believe needs a new crankshaft. A guy I know has a good bottom end from another non-efi Indy 500 motor. Can I use this bottom end with my existing top end and efi setup? I've been told that some of the early POLARIS efi engines used a different oil injection setup. Please help me figure this out. Thanks...

Sorry, all I know about the 500's is the EFI side. Nothing about the innards of the engine.
