Saving 71 Demon...

Wow. That's a heavy project! For a mild engine build, what do you think about the 904 Torqueflight instead of the 727? It's what my 1970 318 Dart came with, and its a smaller and lighter unit that is plenty strong for the job. Truth be known though, I'm slipping a 200-4r into mine for the next buildup.
It's a 340 car I should keep the drive train it came with. I was thinking of OD for as much as I know everything about GM trannies.. the 200 is good and can be built to be even better but the proper case needed to build one that will last are difficult to find and gm parts in a in a mopar.. not really my flavor. I have built some older fords that were built ford tough with chevy stuff but I just couldnt do it for a dodge..
