Is a 7.25 rear strong enough?

Just a FYI. I got lucky and just happened on a 8 in Ford pumpkin at a swap meet. Had 4.10 gears with a mini spool. $200. Two days later went to a junk yard for some items, and believe it or not, sitting on the ground just inside the gate was a 8 inch housing (drum to drum). it was the correct width for a "A" body. $100. Did a complete brake rebuild (new everything), and have about $550 total, in the rear. The housing is from a 1976 Comet. Spring perches are 43 inches. Don't remember the drum to drum width, but is just a little wider (1 1/2 - 2 inches) then the "A" body (wheels can correct that). 5 on 4 1/2 bolt circle, 10 inch drums. "A" body e-brake cables fit. Easy swap if you can find one, and a lot cheaper then a 8 3/4.
PS: There are other 8 in Ford rears that can work, just have to measure, and make sure you get 5 lug rears. Some were 4 lug.
