Don't know for Dodge, but 1933 was the first year for inserts for Plymouth. Wouldn't surprise me if it was the first year for Dodge too but I don't have any references on that.

Does anyone know if the 1932 Dodge DL six had babbit or insert bearings? All I can find listed for inserts is 1933 and up.

Thanks.

i check my copy of the dodge story and it didnt say anything..my '33 chrysler has them for Chrysler the first year for inserts was '34..there is a guy on the aaca forum..keiser31??? who was a '31 dodge..and he might know more..if it is a babbit motor is not as big of a deal as some people think..my '33 was sitting for 40-60 plus years, filed the points and gave it a tune up..runs like a champ..many people told me that for some reason the Babbit bearings would go bad from sitting??..of course if they are bad it's going to be expensive to do because i'm up in seattle hardly anybody does them..but you might find somebody easier?? my advice to anybody is get an education on them before you lay down any coin..:cool::)

Plymouth got insert bearings for 1933. Dodge and DeSoto for 1934, Chrysler 8 cylinder for 1933 and Chrysler six for 1934. The Plymouth six was new for 1933 while the 25" block for DeSoto and Chrysler arrived for 1934.

Not surprised the 1933 Dodge 8 used spun bearings as it was the last year, but I always thought the 1933 Dodge six was the same block as the Plymouth.

The insert type was described as stub-backed babbitt while the 1931 and earlier used poured babbitt bearings. The 1932 and non-insert 1933 engines used spun babbitt bearings.

Actually the Chrysler and Desoto six 25" motor started in 1937.  The Chrysler / Desoto six from 33 thru 36 was a

24 1/2" motor.  Kind of an in between engine. Few parts from the 33-36 fit the 37 thru 55  engines.  I've made it my

part time job  to figure out these engines since I have a lot of them.  All of the engines I have, have bearing inserts.

All bearings except the rear of the cam for some reason...

Trying to figure out if a 1931 DeSoto SA engine would interchange with a 1936 Plymouth P2.

How are they different?  How are they similar?  Found a few specs, but so far all I know is that the DeSoto was 205.3 CI, and the Plymouth was 201.3.

OK. Since I have the catalogs from McQuay - Norris which was a major supplier of engine and other car parts. The following pages were taken from their 1914-37 catalog and I have listed the information in order as DPCD  so Dodge, Plymouth, Chrysler then Desoto. I am not an expert on engines but hope this provides some info and the more experienced members can get specific on the topic.

the second set of sheets is also from McQuay-Norris and cover from approx 37-59

Enjoy the data

Doubt it but only based on speculation: I'm guessing the DeSoto would be using a 25" long block while the Plymouth definitely uses a 23" long block. And this is before the Windsor, Ontario engine plant came on line so there was no need for a Canadian "Plodge" (Plymouth with Dodge badging) that could hold a 25" long engine.

Not saying it can't be done, but I'm guessing it would take lots of custom work to fit it. An easier fit would be a '50s Plymouth 6 with larger displacement, higher compression, etc. than the '31 DeSoto.

A friend in Oregon put a 36 Plymouth engine in his SA.  he used the 36 bell housing and transmission  Nice fit.

I bought his original SA engine and a member of this forum now has it  and a number of new parts. It was a good runner.

We are both in western Canada so shipping would be costly.  I will give you his name if you send a PM.

Thanks guys for the replies.  Actually, I was trying to help the guy with the 1931 DeSoto:  

I have a 1936 P2 engine available, in Illinois, and was wondering if he could use it in his 31 DeSoto.  Looks like Dones475 and dpollo need to connect!

Thanks for the replies.  Dave T.

Has the original poster or anyone else look at the attachments in which I listed the various bearing that were used on the DPCD cars and trucks. I was hoping this would have answered the original posters question regarding engine bearings.
