174/177 supercharged small block, where to start?

Not sure really, maybe the next one down 1190. I didn’t mess with the rod adjuster. you might be able to get away with the standard belt, get the HD if ya can.

A question for you all, how does the idler pulley come off of the tensioner bracket? I removed the snap ring, hoping the pulley would slide off the shaft so I could put my 10 rib on there, but it doesn’t move after a hard pull, light tap with a hammer, a pry with a screwdriver, is it pressed on there?
