Trying to locate any small block poly that can be rebuilt. Hard to find in south Georgia. Any help will be greatly appreciated.
Hope this is in the correct place and allowable.

Got a line on a complete 1955 DeSoto with original transmission. Engine turns over. Stored since 1960 when car was totaled. The guy wants 600 for everything.

Rusty,

You can easily use any of those tranny's behind the hemi or poly block. Chrysler, Plymouth, Dodge, and DeSoto all use the same trans adapter style. Yes, you could say that the bolt pattern between the blocks and tranny is the same... only different.

The tranny bell will bolt into most of the holes on the block directly through holes in the the adapter, but there are a few dedicated screws that also bolt only the adapter to the block and a couple of screws that bolt the tranny only to the adapter. The adapter is registered to the block with the existing block dowel pins and the tranny is likewise registered to the adapter with its own pair of dowel pins.

It's a pretty straightforward deal but it requires that aftermarket adapter plate and a crank flange spacer too. Many companies make them and they may look a little different but they all accomplish the same end.

The crank flange spacer is machined with the correct register to fit a 426 hemi flexplate (8 bolts.) That gets it all spaced right and bolted to the converter. Add a tranny cooler and your wiring and it's a done deal.

Good luck!

Dave

You wern't clear on that. Probably help if you posted where you are. Plymouth A Poly (318 family) or the Dodge hemi based Polys?

I am stumbling through this quagmire of information. Obviously need some good direction. So, this what I want to do: Put a poly, sounds like it will need to be an "A" block Plymouth, 277, 301, 303, 318, Plymouth or Dodge, in front of a 40RH, 42RH, 346RH transmission with a 2 or three wire OD control.
In the way past I had a Plymouth 277 and it was supposed to bolt to the early torque-flite The LA engine is said to have the same bell housing pattern as the "A" small block. Fake or fiction?

I am in south Georgia, but willing to have the correct combination shipped, as a unit or peice-meal

Will a 55 Dodge Super Red Ram bolt to the transmission I want to use wwith out an adapter?

I am conceding to the wiser minds.

All of the Hemis (except 51-3 331), hemi based Polys & "A" Ploys up to '61 have the same bell pattern & crankflange. There are different OEM adaptor plates between the early & late ring gear tooth count. All 62 & later s/b trannys have the same bell pattern. to put a '61 & earlier engine on a '62 & up tranny get the 392 to what the tranny you have adaptor.

Not a bad price. OEM tranny isn't in much demand unless you're restoring a car to original. An adaptor, available from a number of sources, & a modern 727 is better. Non Desoto Hemis can be converted to Poly & you can sell off the hemi heads to cut costs, hemi pistons have to be changed also. There are no Poly heads for the Desoto because the '57 Desoto Poly is based on a Dodge Hemi block.
