I was wondering if LT1 belts, pullies, and accessories are mounted the same as any of the Gen I small blocks (short water pump, long water pump)? I know some of these are listed for motors with electric water pumps, seems like they would work. Side note, would a crank pulley from a gen 1 small block work, or would it be needed to line up with some of these?

Do you have any idea if this would work? It looks the same as some I've seen for LT1s...
MOR-63842

or this one (I honestly can't picture out it mounts, so I don't have a clue if it would work)...
Water pump mount SUM-G4017

or...
MCH-22003


There's a couple others, I was wondering about. I just looked up a mid 80s suburban w/ V8 on summit racing to get a gen1 small block.

Would I have to swap to a different alternator?
