I just bought a 1970 Judge 4 speed off Ebay. I am trying to figure out some issues with the engine and trans. numbers. First the engine, the car should have a WS Ram air III. It does have the WS code and the serial number matches the car but... the casting number is 9799915 which should be for a Ram air IV. The 5 at the end is also stamped into the block and not raised like the rest of the numbers. Now with the trans., it has two serial numbers and two casting numbers. One set matches the car and the other does not. In fact the other cast code ends in a C which would be an M22 which it does not appear to be. The date codes for both pieces are 8-69 and the car was produced 12-69. Any help would be appreciated. Are there any experts that I could contact to clear this up? So far Googling hasn't helped.
