I don't know anything about circle track 360s. Do they use pipe fittings like that?

They seem awfully heavy and weak, especially that closed nipple.

You can run a external belt driven pump with a wet sump pan, that what I did with a 572 BBC I used to run. It broke pickups off, it broke entire oil pumps off even with the brace installed. Tire shake in a dragster is brutal. I can't imagine a dirt track is any smoother?
