I use to own a 1970 "T" Bird and the problem with that was it had a 460 in it, and what really was going on, that year of "T" Bird, with the exception of a few (who knows how many 100's) came with a 429, the 460 version really was a "T" Bird body mounted on the Mark IV which did have a 460. Once I got that figured out, I would go in and order parts for the Mark IV and take them home and put them on the "T" bird. So. take a look at mounts for the Mark and see how they look compared to the ones you have.
Sometimes, being old has its advantages.
