dry sump oil pump question

ALOT of the 80s GM products with the 307 Olds engines used belt driven vacuum pumps. I am sure you could adapt one.

when I was looking to just this with a "smog" or "air injection" pump I had a really hard time finding one that did not intake thru the front pulley. the bronco ended up being the only one I found.
