Tech Question

Dave Gardner, Greencastle, IN, 1967 Dodge Dart GT, 318

Im wanting to put a 383 or 440 in this dart, I have a 904tranny, will these size motors work with this 904 transmission?

The smallblocks (LA273-360) and the big blocks (B350 thru RB440) haveentirely different cylinder block rear face bolt patterns. So thetransmissions cannot interchange. And, while the big A-727 transmission wasbuilt in numerous versions, including ones for G, LA, and B/RB engines, thesmall A-904 (originally designated “TorqueFlite 6”) was never built in abig-block version.

You need a big-block 727 trans, easily identified by large numbers on theside reading: “A-727-B”
