174/177 supercharged small block, where to start?

Okay. I finally found a 1/2 inch shorter belt after searching high and low. With this belt, I was able to move the tensioner over one set of holes, and like was suggested, install one bolt, then lever the tensioner up and install the other bolt.

The tensioner nut where the cotter pin is, now no longer rests against the tensioner body. I think this allows more travel for the tensioner to take up belt slack.

I went for a test drive and it seems to work. I can downshift aggressively and the RPMs come up and the belt no longer throws.

Here’s a short video, the tensioner moves and takes up slack. It never used to do that.
