Well, with the grinding work done I could mock up the installation of the saginaw pump. I think it is going to work just fine. Here is a picture of the pump as close to the block as it will go:
With the grinding, I have plenty of room to tension the belt, here it is as far away from the block it will go:
I do need to get a 1" spacer for the bracket where it attaches to the water pump. The one that was there had to move over to alternator side. Unlike my water pump, I can use my 1F alternator but needed to space out the tension arm so it aligns with the ear. Here is a picture of my SST (nuts and washers)for determining spacer length:
This project is not done yet, but it feels good to post up my progress so far. More to come later.
