My '37 P4 engine is bad and it will take some time to fix it. I found and bought a complete 1936 engine and transmission assembly from a fellow converting to a hot rod.
I want to install the '36 engine in my '37 but noticed the clutch release fork actuating system is totally different. No problem I thought, I'll just use my clutch release fork from my '37. Then I found the place the pivot shaft and ball mount in a different place on the bell housing so that won't work.
Looks like I will have to change out the bell housing, clutch and all. Does anyone know if I will continue to find differences beyond what I have stated and seen so far? Everything else looks the same except a generator mounted regulator which I can work with.
Thanks,
James
Ok, the '37 bell housing fits the '36 engine. I have completed the bell housing swap, the flywheel, clutch and clutch pressure plate.
I was going to use my '37 front mount since it is new and the '36 front mount is in bad shape but they are different. So, don't buy a '36 thinking you can use it on a '37, it will not fit. The stud spacing on the rubber portion is different. I will do a temporary repair on the old mount.
I hope to install the engine tomorrow and see what fitment problems I run into trying to hook everything up. I already know about the generator mounted regulator. Mine is firewall mounted.
Stripped to the bare block, the P2 and P4 engines are virtually identical. You can redrill the front mount plate if you need to use the earlier mount. Some of these engines did not have the heater outlet on the cylinder head drilled and tapped. 36 engines may have a vibration damper on the front pulley. Both engines have a 3 1/8 bore and 4 3/8 stroke for 201 cubic inches and 82...or was it 84 HP Blocks were painted black and cylinder heads painted aluminum. A real aluminum head was optional.
