What did I buy?!

"Find and A833OD for it rather than the sid A833. That will give you acceleration and mileage."

I heard that the OD trans wasnt as tough amd shouldnt be used behind a V8? Ive got a 833od out of a late 70s slant6 truck, as well as an A833 out of a '64 Dart GT which has the steeper 1st gear(3.09 vs 2.44-2.66) than the later non od 4spds. And performance is more important to me than economy. Thats why Im pulling the 6 for a 360.

Also, what does a 360 .040 over end up being in inches?

And I think I will pull the top end to see whats in it.
