Well, I had a chance to go out to the engines today & here is what I found.
The chrysler motor is an industrial motor of some sort (uncle thinks it may have come from a combine?). The motor is complete exept for the carb. On the upper left corner of the block there is a flat spot with this stamped on: IND7 4536. On the lower left corner (under the starter) there are these cast numbers: 870729-8. The head number is: 954412-1. There is a plate on the right side, just under the exhast. For the most part its rather unreadable, but there is something about it being a chrysler industrial motor, etc. However there was some numbers stamped on: IND 7-60 4708. These numbers were hard to read & I'm not all that sure I got them right.
The dodge/plymouth is complete exept for the starter. On the upper left of the block there is this stamped: 84285814. On the lower left, just under where the starter would be, there are some cast numbers: 1484929-3. I couldn't get all of the head number as there was some sorta linkage in the way, but this is what I could get: 167633-?. Also, just under the distributor was a number "59" cast on, is this the year the motor was made?
I hope that I got the right numbers. I did clean the area around the engines to take some digital pics, but other than that I didn't do anything to them. My uncle isn't really interested in getting much for them, to tell you the truth if someone just showed up he'd probably just load them up & give them away. He's already done the same for me with a couple of the ford sixes that were siting there. Take care,
Edwin
