Pulled the oil pan off the 351w I picked up (D9 block)

It's got an aluminum oil pump (with a Ford part number).....never seen one in aluminum.. is it a year thing or ?

I haven't pulled the cover to inspect the gears yet but is this pump the same/better/worse as a regular cast version?

Should I use it (pending gear inspection) or replace it with an M83 ?

Common. I bet it has a C8 part number on it.

When i yanked the pan on my '88's 302 to build it up, i was surprised to see an aluminum oil pump on it. I still have it kicking around if pics are needed

Interesting...

All the ones (302s and 351s) were always cast but maybe they were all later models, I couldn't say

So no reason not to use it of the gears check out?
