No problem. How much power are you looking to make?
Fyi, my buddy ran his 8-3/4 behind a 500 stroker and 727 into the 9.40's in a all steel 69 Dart pullin the wheels a bit. The rear was unbraced but upgraded axles and such.
Eventually i'd like to put at least a well built 408 in my Cuda, prob around 525 Horse....I also thought about stroking a 440 I have, but I'm leaning toward keeping it a small block car.. I have not an ounce of doubt an 8 3/4 would handle that, I originally went for this rear end because the guy thought it was a Dana....
