Ok, stumbled across this thread while getting an idea of the chain routing.

Wow, exactly what I was looking for, Thank you Cell! He made all of the mistakes I would have & still managed to get it done. While the most effective way to learn is from mistakes, it is far less painful if you can learn from someone else's! This write-up is awesome, I think between the fsm & this I should be able to do what I'm trying to get done. Although I'm a little envious of all the room that a 67 pickup affords! I'm not usually this gun-shy about diving into a repair, but I certainly realize that not paying attention to detail and doing something stupid on internals can cost you an engine real quick. Damn, I just put a new lower pan and gasket on when I did my turbo drain, probably going to have to pull it to see if I can find those "twelve little balls"
