Ok, so it doesn't matter if its a 904 or 727, but I will need a small block tranny to go with the engine, correct? Also, aside from the standard motor mount changes, is there any differences mounting the small block tranny in place?
They mount in the same place, so you shouldn't run into any issues there. You may need to address the driveshaft if there's a difference in the length of the transmission. A 727 also takes a different yoke than a 904. If you stick with a 904 then everything should bolt back up BUT...what rear end do you have? If it's a 7 1/4 then you might blow it up when you drop a V8 in. New rear end = new driveshaft.
All said and done, it's a pretty straight forward swap. Going from a slant to a small block is pretty easy.
