53Chevy5, you might look at getting a different pulley for the pump and re-routing your serpentine belt to spin your pump CW. That's how March does theirs, using an up & over the top belt route. A 348/409 pump is expensive anyway, but when it's reverse rotation it becomes just about one of a kind. Gotta think about the future, and what happens when you need a pump and you're in Slippery Rock, or worse. I looked over on Rocky Hinge's site to see what they do, but they only do SBC & BBC, nothing for the 348/409.
