55 Fargo Posted October 4, 2009 Report Posted October 4, 2009 Stevesplym,is nearby,he could use the OD trans for his Plym, and a spare engine is nice to have.... Quote
RobertKB Posted October 4, 2009 Report Posted October 4, 2009 Reg, I agree. Great starting price and I sure could use that overdrive in my '38 Chrysler. Spare engine would be good also as it is the long block, same as my car has. Looks like it came out of a pretty decent car as the engine looks good and still has lots of paint. Probably another rod project. There soon won't be many original cars. Guys will rod anything....good originals and restored cars. Sorry, just my pet peeve. Quote
Reg Evans Posted October 4, 2009 Author Report Posted October 4, 2009 I agree Robert. I would always choose a nice original with some bolt on mods over a hot rod. Sure hope he's not putting a 350 chivy in that DeSoto coupe. Quote
steveplym Posted October 4, 2009 Report Posted October 4, 2009 Stevesplym,is nearby,he could use the OD trans for his Plym, and a spare engine is nice to have.... Wish I had a place for it I would be interested. It never hurts to have extra parts around. Troy is about 1 1/2 hour drive for me. Quote
H Suhling Posted October 4, 2009 Report Posted October 4, 2009 Not to far from me either and the overdrive would be nice in my truck also if it would fit. Harvey Quote
RobertKB Posted October 4, 2009 Report Posted October 4, 2009 The overdrives on the '37s through '39's are a lot different than the later overdrives in the '50's. I am pretty certain that a '30s overdrive will not bolt onto the later trannies in the '40s and '50s. Quote

I am pretty certain that a '30s overdrive will not bolt onto the later trannies in the '40s and '50s. That is what I was wondering. It seems like a different animal. Quote
Plymouthy Adams Posted October 4, 2009 Report Posted October 4, 2009 I do not own any older flatheads that 41 so I am not sure when the last of the floorshifts were out there.. Quote
Young Ed Posted October 4, 2009 Report Posted October 4, 2009 For plymouth 39 was the last year with the roadking being floor shift and the deluxe having the new column shift. Quote
Niel Hoback Posted October 5, 2009 Report Posted October 5, 2009 Looks like somebody got it for $99. Dang. Quote
RobertKB Posted October 5, 2009 Report Posted October 5, 2009 Whoever got it got a deal. I have seen those transmissions go for over $1,000 on ebay and that is for used ones of unknown condition. Quote
Plymouthy Adams Posted October 5, 2009 Report Posted October 5, 2009 if nothing else, the tranny I think has the tall second gear..easily transplanted in the later case.. Quote
desoto1939 Posted October 5, 2009 Report Posted October 5, 2009 On this unit there are several selinoids and a push pull rod that hooks to the steering column. Great buy for who ever got it. It would have fit in my 39 but you would have also needed the drive shaft that went with the car to make it a complete unit since the drive shaft is shofter that on the regular car without the overdrive unit. The overdrive had the cross style universal on the front and the detroits on the rear at the pinion. Yes he is rodding the coupe. Rich Hartung Desoto1939@aol.com Quote
Reg Evans Posted October 5, 2009 Author Report Posted October 5, 2009 Rich, what would the hp and ci ratings be on that DeSoto engine. Sure would have been welcome under my 38 Dodge coupe hood. Quote
desoto1939 Posted October 5, 2009 Report Posted October 5, 2009 The big block engine had a standard hp of 92 and with the aluminum head you would get 100hp not sure on the ci. I have a MOPAR factory Aluminum head that can be used for any big block enginee from 1938 and up. It has been milled and is in great shape. the small block dodge/ply had a hp of 85 which was equal to the ford v8 engine of that time. So the Chrysler/Desoto engine produced more HP that the Ford V8 and had juice brakes and was much easier to work on the engine because of the location of the Distributor on the ford was so close to the fan blade that you had to send the dizzy out to be timed. rich Hartung desoto1939@aol.com Quote
Don Coatney Posted October 5, 2009 Report Posted October 5, 2009 Also remember that a long block Desoto or Crashler engine will fit but not be a diredt bolt in on a Dodge or Plymouth unless you have a Caniadian made car. I have a Desoto engine in my Plymouth but several modifications were required to make it fit. I am glad I installed it. Were I to do it again I would find a Crashler 265 CI engine as opposed to the smaller Desoto 251 CI engine. Quote
Frank Elder Posted October 5, 2009 Report Posted October 5, 2009 Don, On the 251 vs 265 is it just the bore size of the cylinders or is it also rods and crank that are different? I know on the 218 vs 230 that the bore is the same but the crank and rods are different, is it like that? Quote
Powerhouse Posted October 7, 2009 Report Posted October 7, 2009 DANG! I paid over $1K just for my tranny! WHAT A DEAL!!!!! Quote
Reg Evans Posted October 7, 2009 Author Report Posted October 7, 2009 Don,On the 251 vs 265 is it just the bore size of the cylinders or is it also rods and crank that are different? I know on the 218 vs 230 that the bore is the same but the crank and rods are different, is it like that? The 265 has a 1/4" longer stroke than the 251. Same bore. Quote
RobertKB Posted October 7, 2009 Report Posted October 7, 2009 (edited) I've got two cars with 251 CID and really like that motor. I have heard from old time mechanics that the 251 CID is a better motor than the 265 CID. Not sure why. Edited October 7, 2009 by RobertKB Spelling Quote
Don Coatney Posted October 7, 2009 Report Posted October 7, 2009 My 251 is now a 255 due to a .030" overbore. Pictured is a 265 that is now a 283 with a big overbore. Imagine that, same displacement as an early SBC. Quote
