Ok. Climbed under the car this morning to take a look. Here’s the number on the pan rail.Yes-there were several different 727's used in any particular year. Let say 1969, 383-2 barrel, 383-4 barrel, 440 standard, like a 440 New Yorker, 440-HiPerf, 440-6Pac, and Hemi all used different part numbers. When automatic cars get messed with, 9 out of 10 times. having improperly adjusted or removed kickdown linkage destroyed many transmissions. Smallblocks are the same way. Post up the PK part numbers on the pan rail, and we can tell you if you have the right trans for your car.
