Default Belt shredder and pump eater

During the past couple years I have been hitting the dragstrip pretty regularly and have had ongoing problems with belts and PS pumps. I'm running the factory '68 timing cover/brackets/pulleys. When I race I undo the PS belt (which knocks about .1 off my ET). This, of course, makes the problem worse. The pulleys seem to be well aligned and the belts appear to be straight.

I have tried just about every belt out there and none of them seem to last. Have tried belt dressing. I had the car out yesterday and spun another belt which had lasted longer than most do. I'm getting pretty sick of carrying around a bunch of belts/wrench/pry bar. How does a guy permanently fix this problem?

I have also had at least 3 different PS pumps (or maybe I should say POS pumps) on this thing. Most are the only I can find -- rebuilds done by "Lares" or "Cardone" and the quality sucks. I'm not interested in rebuilding mine. What are my options for a new pump? Are there any newer pumps that interchange?
