I doubt it unless you show me a picture. A 72 block would have been made for a 72 car that has different style engine mounts. Three bolt holes doesn't accommodate both styles. Go back and check again Drew. Why else would they sell the kit?
I thought the issue was when you wanted to put an early block in a later car. Then there weren't the right holes to fasten the later engine mounts to. I thought he later blocks have enough holes that a pair will fit the '68 mounts. I have a 71 engine that has '68 style two bolt motor mounts bolted on and it was in the car that way when I bought it. Nothing was rigged. Transmission mount was stock and there was nothing home made or welded to make it work.
This is a '71 engine, code E071 by the distributor?
