Rear end ?
Is there any reason not to use a 89 8 lug 3/4 ton ford rear end for a hotrod?Seems like it would be bullet proof or close to it in stock form?.500hp /500tq tops.Its gunna take longer than u thought and its gunna cost more too(plan ahead!)

yup. Trying to get all that mass rotating will make you 500 horse feel like 300. Bullet proof maybe, but you can get that with a lot less weight.theres no foo like an old foo

I much prefer the dropout 9" Fords, easy to have another set of gears or two set up.... I suppose it would be strong, but all the extra weight and sheer mass would probably negate any gains... I built a car for a friend of mine in '95, close to 500 passes on it now and still the same pair of 40 spline Moser axles. The current engine is 500/500, it's had bigger engines. It has gone through a couple of pinions, however!!!Yesterday is history, tomorrow is a mystery, Live for Today!

All depends on what the basic unloaded drive pinion torque is. The HP will increase pretty linearly with speed.

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
