I’m about to replace the timing belt (among other things) on the spare 74 engine before dropping it in. I was about to mark the old belt and pulleys but the cam pulleys don’t line up like the diagram in the manual. I turned the crank several times and made sure it was at TDC.  

The cam pulleys always line up like this when the timing mark on the crank pulley is lined up and #1 TDC:
 

Here’s where the timing mark is:
 

The diagram shows the “IN” mark on the intake cam pulley lining up with the “EX” mark on the exhaust cam pulley which is definitely not what I’m getting.  

I was told this engine ran well before the PO bought it. I’ll mark the old belt and pulleys before removing it. The belt looks very old, maybe it jumped a tooth (or several)?
