I'm looking for some insight on how to proceed.
Here is my situation:
The truck came with a Chrysler 25" engine out of a '49 Royal or Windsor with a Spitfire head. The PO had it all just sitting in there and hadn't done any modifications for the radiator yet to make it work in the 23" engine space the truck has.
It had this transmission in it:
The spline is thick, it's 1 3/8" and the smooth end of the shaft is 2" long and 3/4" thick. This is the transmission I want to use if possible.
The engine that was in the truck has an 8 bolt crank.
The engine I want to put in the truck is a 23" 230 from a 1953 M37 truck that was in my P15 car. It will bolt right in to the truck with no modifications necessary. I want to put the Chrysler in the P15 with the Spitfire head in a future project, and I know there will be modifications per Don's threads with his DeSoto engine.
It has a 4 bolt crank. The transmission that worked in the car has a 1" spline and the smooth end of the shaft is 2 1/2" long, 3/4" thick.
The truck came with an additional engine and transmission. The extra transmission is this one:
It has the same size spline as the car transmission of 1", but the smooth end of the shaft is 2" long which is a 1/2" shorter than the car transmission.
So here are my questions.
1. Will an 8 bolt flywheel work with a 4 bolt crank and not cause it to wear or break because of the differences?
2. Could I use the 4 bolt flywheel that came with the 230 engine and just mount the bigger clutch and pressure plate to accommodate the bigger transmission? Since the shaft ends are the same thickness if that works, it seems to be the cleanest option.
3. If I can use the 4 bolt flywheel, will the bigger transmission work ok considering I do have the right clutch and pressure plate for it?
4. If I can use the 4 bolt flywheel, will the 1/2" shorter shaft end of the truck transmission be an issue?
5. Is there any advantage to using the smaller spline extra transmission? I have no idea if the transmission even works. It was laying in the back yard of the PO.
I've been reading many threads on flywheels and I've seen where some have used a 4 bolt flywheel on a 8 bolt crank, but I haven't seen the opposite to my recollection.
