Packard Forum Index » Pre-War (1899-1942)

I am interested in acquiring an available 237 engine from 1937 to install in place of my 245 engine in a 1941 110.
Would you happen to know if the flywheel from the '41 will bolt up to the '37 ?
The Packard parts manual shows a difference in part numbers.
I would like to use the '41 gearbox mated to the '37 block. Is it possible?
Any other pitfalls with this swap?
Thanks to all.
Tom

Anyone?
Should I post this in the "general discussion" part of the forum?
Thank you.

I think you are in a good part of the forum but it seems no one has an answer to your question. I don't know if Flackmaster has been around to see your question but he specializes in parts for those years so might have an answer.

I'm not sure about the flywheel differences but I know that a complete 1941 six will bolt in to a 1937 115C as it did that many years ago.
There may be a clearance issue between the 1937 water pump and the 1941 radiator due to the different style of pump.

Yes, the 1941 transmission will bolt up to a 1937 block.

Edit: The 1937 water pump is about 7/16" longer from the front of the motor block to the end of the shaft. The pulley and fan are also different than the 1941 and will not interchange.
