Default Question on setting oil pump pickup clearance...

How do *you* determine how far from the bottom of the pan to tack it in place???

Leave it loose and let the pan "push" it up in place???

Tape a shim of some kind to it & push pan against it???

Carpenters rule & eyeballs???

...???...

My book, "How to build the small block Chevy" says to let the pan push the pickup down, then remove the pan and push it 1/4" in the same direction. This is what I did and had it tack welded into place.

Installed parallel to the oilpan rails I found that the pickup would be about 7/16" off the oilpan bottom. I installed mine in this position.

This is what I always do.
