Lots of variables. Like how much do you want to spend. I suggest picking up a MOPAR Performance catalog and couple brand specific magazines. You should be able to swap the engine just by changing motor mounts. The Tranny has to be changed to a small block. Hard to find parts for the 8 1/4. For performance i suggest upgrading to 8 3/4 (depending on horsepower). Bigger is always better .

i changed one a few years ago,you can't just change motor mounts,drop out the whole front end assembly,the hardest part is the arms running to the back is getting the clips off,i put a 318 in mine used the same trans. and rear end,but mine wasn't for racing,
