How can you identify a mopar 727 big block transmission? I dealt with this with my 1965 Chrysler w/ 383 V-8. At least for my car, the big block version is stamped "727 BB" and the case is longer. I recall 35"L from front of case to end of the aluminum (not rubber driveshaft seal). Everything looked good on the rebuilt transmission, but when I unwrapped it to install I found the speedometer hole was too big and it didn't have the cable shift input. Under the gun with a moving truck coming, I had mine rebuilt locally, which didn't fix the "morning sickness" problem (fluid draining back from torque converter?). I since found that 1965 was the year Mopars converted from pushbutton to column shift but retained the cable shift of the pushbutton (1965 only). If I ever have to replace my case, I am guessing an earlier big-block transmission would work if I can't find a 1965.
