my first mopar, will i love it or hate it?

Welcome, and cool Duster! For a bb, you will need a 727 trans with the bb bolt pattern on the bellhousing. Schumachers makes engine swap mounts to basically bolt one right in. A bigger radiator would be a plus, and the more cast iron parts that you can swap out for aluminum parts, the better the f/r weight ratio (water pump, housing, intake, etc). Looking forward to more pics!

I'd also add better springs and maybe T-bars if you don't like the bouncy ride you kind of get with the /6 bars. Also the rear of 8-1/4 will be fine for normal driving, rare beat downs and the 8-3/4 I have seen is good for low 10's and high 9's. And the 9's is pushing it if the car is still heavy. After that, your a gonna need a DANA or the Ford 9.

While the swap is easy, it just costs MONEY! LOL! I know, what else is new.....:coffee2:
