First you need to find out if this is a reverse rotation engine.

THIS IS A STD.(LH) ROTATION ENGINE. BUT THANKS FOR POINTING IT OUT

I am running a marine BBC no signifigant change had to be made other than the oil pan. and it had some oil cooling system with a remote mounted filter so I had to get the right adapter for the screw on filter. other than that eveything else worked. def check your flywheel to make sure its compatible before dropping it in though just to be safe
