I like Melling 10778 or 10778c pumps. Although some guys here dont like the "C" pumps, I have used them on 3 engines recently with great results. There have been claims of the "C" pumps causing pressure fluctuations at idle speeds, but the 3 engines I did, didnt experience that problem.

Vinney P and I both concurr!
Raylar uses the Melling 10778c on our BBC engines exclusivly and we have nothing but excellent results.
These pumps are the best because they have bearing support at the top and the bottom of the oil pump gears, which stops gear seperation at high loads which is why you see uneven wear and gouging on the old style pumps in the cover.
We do throw away the extra spring in the box, don't use it its not right or even close and we do weld the pickup tubes in place carefully (not to much heat) with the cover off and then re-install the cover and torque cover bolts and check pump feel under rotation again.
These pumps are reasonably priced and they represent the best value in BBC oil pumps today!
Best Regards,
Ray @ Raylar

Plug it or tap the hole and install a 1/2" pipe plug. I tap and install the plug.
Also, I use a M77HV pump. It is the only pump I have ever used for over 20 years and have not had any troubles with them.

I had a after market bolt on style pickup, it was not welded on and cost me a motor. The bolt worked out, pickup fell off, and BOOM, two rods through the side of a $12k motor. now I weld it on no matter what.
