BBC question

any way to tell what motor it is besides casting number in the back or boss on passenger front? Manifolds(intake and exhaust) not original.

Re: BBC question

Casting Number or boss as you noted are the easiest ways to tell. Otherwise, get a mic out and start measuring cylinder diameters and checking the crank for stroke. Externally, there are no differences that I am aware of. This is all assuming Mark IV.
