I see the busch on the pump is it a nascar pump? And did you ever use it yet? Only reason I am asking is I thought the pressure stages where to small for BBC.

It was a nascar pump we bought from Ilmor. We rebuilt it and changed the pressure accordingly. Also changed the drive and driven pulley size to drive it at 60% as I won't be spinning it nearly as fast as they were. We had to buy one new section as one was scored from Some debris. Not bad, but the section was less than 100 bucks so we bought a new one.

That's one thing nice about those pumps parts are priced rite and they work good.

I was shocked at how reasonable the parts were. I bought a pressure spring, all new O-rings, a section body and new AN adapter fittings as the ones on it were "quick connect" of some sort.
The pumps are expensive new, but oddly enough parts are priced right.

The heat exchanger (oil cooler) bypass valve.
