DeSoto 236

[jyinger]

How much do the 1940's Mopar flatheads weigh--esp. the DeSoto 236, 251--?

..a bunch....

I have never had one on a scale but I'd guess that they will be in the upper 600 range and I would not be surprised if they went past 700.

I agree, I suspect they weigh at least 600 lbs. Never swapped out a Chrysler flat head 6, but I have done a couple of 1950's era Chevy 235's and they were real heavy.  They don't make them like they used to.

I know a 230 Dodge flat 6 will flex a 750lb engine stand. Now it is a cheapy stand.

I just shipped a Chrystler 251 (same as Desoto flathead)  with all accessories, bellhousing and fluiddrive transmission and it was calculated to weight 735lbs.   Shipping company was upset because I was quoted by my declaration stating it weight 450 lbs

You did not state why you needed the weight info for a DeSoto engine. If you are considering swapping a DeSoto or Chrysler six engine into a Plym or Dodge it is a piece of cake, especially on the '46-48's.. The DeSoto/Chrysler engines are commonly referred to as "long blocks" they are approximately 2" longer than the Dodge/Plym.
The Dodge chassis' are drilled for the "Spitfire" engines, Chrysler sold the Dodges as Chrysler's in Canada, and most likely several other countries. I put a '48 Chrysler Spitfire engine in a '48 Dodge a few years ago. Had to move the radiator to the front of the core support...

I'll pay attention, someday. My Chrysler 251 Spitfire is 25". So is that the same as DeSoto 251 with a different head?

The Desoto /Chrysler / Dodge Truck engine your referring to is  238 ci,  250ci and 265.  They all weigh within 2 pounds of each other. They are all 3 7/16" bore and use different rods and cranks to get to 238 ci - 4 1/4" stroke,   250  -  4 1/2" stroke and 265 -  4 3/4" stroke.  While the Desoto never had a 265 ci motor stateside,   after Chrysler and Dodge Trucks have them in 1952,  you could but the 265 in the 1953 model year in Canada,   just like  Plymouth could be bought with a 250 ci motor later.   Yes I realize people often refer the 250 as a 251 or 252, but I am just going by what Chrysler called them.

In any case those engines are 422 pounds.  That is the engine..  Not bell housing, not intake, exhaust and carbs, pulleys, starter etc, but does include the distributor.  I haven't scaled one with all the accessories on it, but someone's estimate of 450 lbs is  likely pretty darn close.

Our 265 engine in our race car,  including the intake/exhaust, carbs, ready to hook up to the bell housing weights 410 pounds.    There is actually a lot of weight you can take out of the engine if you really want to
