It's a good day today. I found the problem. I found a threaded hole under the pushrod cover. The hole is between the 3 & 4 cylinders and is inline with the oil passage leading to the top end. When I spin the oil pump I'm getting oil out of the threaded hole. Now I need to know if something is missing, or if I can plug the hole. My service manual isn't too clear on this.
By the way, good to know regarding casting numbers. the numbers on the block above the starter are CON3 J41. If it makes a difference the numbers next to the distributor hole are F1103J.
