1940Century

Thanks to everyone, I now have good info, to hopefully come up with a motor. 1940Century

So the block in the 1936 Airflow has an outer jacket on the drivers side, no cylinder castings and smooth with freeze plugs, and is 24.5" as measured on the head. So is that the same block as the later years?

Thanks for your response, So the larger block engines, 25" long are not all the interchangeable. That was my understanding? But I am not very familiar with those engines. Trying to find an alternative the the original 36 Desoto airflow engine as the heads are very hard to come by. Someone in the Airflow club was making repo heads but they are extremely expensive? I have been told that there was a lot of engine exchanges in those early years??

Thanks Greg, Thats what I needed to know, I will look for a Desoto or Chrysler engine? Mike

Hello, I'm looking for an alternative for an engine swap on this Airflow. Head is cracked and 2 spark plug holes are stripped? Engine is froze up. Hoping to find an alternative. I'm told that 36 to 54 Mopar engine blocks were all the same?? I am ok with getting a different motor installed if one can be sourced, any info would be appreciated?
