I'm not gonna be putting that much horse through the 12 bolt 450 tops. I can machine it to fit the bigger pinion from a car easily so. This will be a while down the road the truck I would be putting it in originally had a 250 3 on the tree so it probly has a baby 10 bolt so anything is better than what is in there. I know a kid who grenaded the rear end in 1984 k10. With a stock 350 other than a holley and an intake. He did a neutral drop though.

Ford 9 inch with Strange axles will outlast a 12 bolt in a high horsepower street application, -- but with 450 hp's, its not gonna matter, the tires (unless they're slicks, and/or you have some chassis mods) are gonna slip so much that it will never bite hard enough to hurt it

Not necessarilly going to have 450 horse but probably not for a long time if it does.
