Is there a low profile water pump for a 360?

@67DodgeDart360 I would suggest going to a flex fan, no clutch. Here is one I purchased at a local Oreillys just to test on my run stand. If it works for you in keeping your car cool, then I would be looking for a STOCK 5 bladed Mopar fan. The fan is a plastic/nylon... I would not suggest using it forever, only as a testing tool, it draws a lot of air through the radiator at idle speeds.

I've been using a fan just like that since 1979, no issues at all
I replaced the a blue version of that fan with a black one. lol
