Discussion of the Early Dodge / DeSoto HEMIs.
11 posts • Page 1 of 1
I talked to a trans repair shop today concerning the tranny swap between my hemi and a poly. After this conversation I think I may just stick to walking. I have a 56 Desoto Firedome that originally was backed by a 2 speed auto. I intend to put this into my 59 Coronet using the 3 speed auto that came in the car. Should this be a straightforward process? Any and all help appreciated. Thanks. Ray
ALL Mopar trannys for the hemi, hemi based poly & "A" Poly up to '61 will bolt on except the 51-3 long tail 331 chr hemis. there were both 2 & 3 speed iron case trannys (PF & TF) available before the change for '62, think '57 was 1st year for 3 spd.
Were these considered strong trannys? I have a lead on a three-speed that could go behind my 330 ci S-24 that we are targeting for 325 HP to go into my F-100. Can the rebuilders put in better clutches and shift kits, etc? Thanks. Gary
You seem to be spreading this around the Threads! in 57-8 TFs were used behind 392s, so they'll handle a 330 Desoto. However parts for the early trannys are getting real scarce, not to mention anyone experienced in working on them. Personally if you want an A-T I'd get a 392 to late model 727 adaptor from Quality Engineered Components & a SB 727. 70s-80s pick ups & vans are good sources.
Thanks George. Didn't mean to upset anyone. Just wasn't sure how messages get to people when there have been no posts for several years. I'll get it figured out. We have the Transmission Exchange in Portland, OR that has parts and knowledgeable techs for the old stuff. Not cheap, but they have been around since the 40's. Good source. Gary
I have decided to stay with the pre 1960 stuff and, therefore, purchased a TF tranny out of a 392 ci 57-58 Chrysler. When checking the fit it seems the bolt pattern on the TF bell housing does not match the adapter plate that goes between the 330 ci Desoto engine and former PF tranny. I could just use the bell housing from the old PF, but it was an air cooled tranny and has gynormous cooling vents which make it appear not very strong (if all else fails may just have someone weld in some patches to fill the vent holes). Was there a different bell housing for the TF's that went into the Desotos or was there a different adapter plate for each car line to mate up with the variations of these hemi's (Dodge, Desoto, Chrysler)? Thanks. Gary
