Ok, I'm not even sure if this belongs in tech or general discussion but we'll try here.
On the J truck in my signature, I need to know if there is a # stamped in the engine block to identify the production year of the engine and where it would be.
Reason I want to know is that a little voice in my head keeps telling me that the engine/trans/xfer may possibly be out of a later model CJ.
I'm actually hoping that it is, as I read somewhere that from about '72/'73 on up the bellhousing Bolt patterns were the same as later model stuff and I've got a chance to pick up a 5 speed trans that came from a 4.0 TJ. Having a 5 speed would go a long ways towards making my truck a more pocketbook friendly DD. This 8.5-9.5mpg thing is rough when you commute 60 miles a day.
