[quote=&quot;John Schwiebert&quot;]The numbers by the starter are not stamped. These numbers are about 3/4 inch tall and cast right on the block. Also look at the tag on the injection pump. Read the complete tag. Also if you have the valve cover off there will be 2 casting numbers under th rocker arms. See once what they are.[/quote]

No numbers of any description near starter But on the other side opf engine  there is 195-20, not sure if the 1 is a 1 or a casting blemish, so either reads 195-20 or 95-20
then below is CHG or CHC 63140 the numbers under the rockers is 196002. hope this helps. (like pulling teeth without an anesthetic isn't it) thanks for your patience
