Tell me how strong was or is you 7 1/4 rear.

I read that the 7 1/4 was junk(weak), specially when compared to the 8 1/4 or the strongest 8 3/4. It can handle abuse from a six but if you change engines, change it, or take it easy! Like said previously, it won't handle slicks. But on the good side, they even came from the factory behind a V8, on the last year they made the Cordoba.
