Yeah, it was a bit of boost. Scared me to death. It was a 6 cylinder Alis Chambers, diesel. I did the camshaft and designed a shaft rocker system for it. Never dynoed, but a good guess would put it a 3500HP.
HB, Cranks, rods and pistons are available aftermarket, but that is all I know of at this time. We do have to do a dry sump for it for someone, I can't remember who.
