we just their "super pro" pump on our 604" BBC in a fast bracket dragster. Seems be working great. Took around a tenth of et's. no more milky oil, no more oil leaks, etc. Only problem we had was their brackets didn't work with our chassis lay out. Seems like everythings that way with dragsters. Can definetly tell its setup for a door car with out any frame rails close to the engine. Talked to the guys out there and they sent us different brackets that no way i would put on the car. Stock BBC chevy brackets basicly. After a few mods to relocate the pump on the motor, a longer belt, and making different spacers it works great.
I'd still say its a good product. Just need to work on mounting ways. I'd look at aerospace components first. they have a simple bolt design that clears basicly everything
Just my 2 cents
