Completely different animals

I've seen these rear ends take over 400hp on the track in a light car with 10" slicks, but would question the reliability for your truck. They are pretty light duty (I believe 7 1/2"), although still better then people give them credit for.

A better choice is a 9" from an early style Ford Bronco It's also narrow, and has lots of bullet proof parts available.

i second the kanook

Doug, Did you take any pic's of the engine swap?
I'd like to see a how to on a V8 swap (if you care to)
I'm looking forward to reading about how it works for you
