yea, you would need a rev limiter for sure... he has a bunch of older stuff, kind f their thing... fun yard to walk as well. as far as i remember the bpo's and caddys all have the same mounts and outside dimensions. remember all the blocks are the same size. thats how they snuck the big motor in the first gto's. that 500 dropped right into place in the regal, and they tranny bolted up as well.I'll check with them, from what I know of the 500's they don't like high r's. That's no bueno in a jet boat, plus the mounts would be different
