I have a line on a 55 dodge poly for my 33 Plymouth coupe. Will a push****on from a 60 desoto work? And if not which ones will? Thanks, Ted
NO! Theres a lot more to the answer though, the transmission would work if you had the bell housing and spacer from the poly. The Desoto should have a big block, all of the early Hemi and Poly engines (except the extended bell housing 331) are small block style bolt pattern so the bell housings won't interchange. Now, all 61 and back Mopar V-8's share the 8 bolt crank, big block, Hemi, and Poly so torque converters do interchange. As you can see it can be confusing! If you want to run the Poly you could buy a trans adapter for the early Hemi and run a late trans. If you need any more info, send me a personal message and I'll help if I can.
Thanks, i thought about the adapter solution but thats not cheap and im trying to put this thing together with stuff ive got or can get reasonable. So it has to be a push ****on from an early hemi or poly? I was afraid that might be the case.
I had the early cast iron Torqu-flit three speed behind my 241 Dodge. I don't think the 727 type fit without an adapter.
Transmissions: All 54-62 (Hemi, Hemi based poly, and A-series poly engines) (not B-RB) transmissions can be used if swapped as a complete package. That means use all of the parts from a single year/application. If you start mixing starters, flywheels, converters, starter mounting plates, etc you will not be happy. Starting in '63, changes were made to the A-series block and crank that require an adapter for the old engine/late trans swap. From a practical stand point; The earlier auto trans units are expensive to rebuild, compared to a later TF. The early transmissions (auto and manual) have an e-brake attached to the tailshaft which can create clearance problems. The early units have an odd-ball trunion instead of a slip yoke on the driveshaft. Good points include '****on drive through '64, although the lack of a slip yoke is an issue. The 63 and 64 models can be converted if you have a 65 model available to get the tailshaft from. The tailshaft can be from either small block or big block application. also, check this thread: http://www.jalopyjournal.com/forum/showthread.php?p=4964058#post4964058 .
Thaks for the info. I knew about the crank differences in the early to mid 60s but wasnt sure about the bell housings being interchangeable between different motors. I think i got a good idea now though.
1962 was the first year for all Mopar lines and engines to change to the aluminum case transmissions, and conventional crankshaft style, 61 and back are the old style. David.
