Title: 1935 engine info
Post by: 35PJ on February 28, 2021, 09:54:54 AM
I'm looking for specs on my engine. 1935 PJ, flat head 6, Block stamp is 632929-3 and has "P3" on the other side.

need to find the factory crank and cam bearing surface sizes so I know what bearings I need to order. seem to be having trouble finding this info.

can someone point me in the correct direction.

Thanks!

There is a boss on the block above the generator which should be stamped with the engine number. That will tell you what the engine is. Or was when it shipped from the factory, if the crank has been turned, etc. then that may not be accurate.

The engine number starts with the engineering code for the vehicle the engine was shipped in. For 1935 the engine number should start with PJ.
