I am trying to build a relaible data base on the post war version of this engine. The basic casting number 641087 and 804380. I am looking for the entire casting number series across the bottom right side of the block (IE 641087-L-W-12-A-N1-CR-N2), the serial number, weather it has an oval serial pad machined on the upper right side behind the oil filter, and if it has 2 or 4 expansion (freeze) plugs on the right side and timing mark location as well as how many bolt holes in engine's rear flange to attach it to the Bell housing and plate. Please include the model / serial of the jeep it came in if known.
Please email this data to me at: email@example.com
1-Engine serial number
