Small Block Oil Pick Up Tube Question

thanks for the information. Based on your work I have taken a die grinder with a carbide burr and ground an inlet so it's closer to center. I plan to drill and tap it to 1/2 pipe so I'm very interested in your results with the Milodon end. Hope it works. I'd love to have a "go to" solution for an oil pump pickup that doesn't restrict the pump.

i tried the die grinder on the pump in the picture. Was able to move the center of the hole down and over from the thin side. When i drilled it the bit headed off toward the thin side. Next time I try this I will remove more material from the inside thick wall first.

Still waiting on the Milodon insert to get here.

So I proceeded on Frankentube. These are before being welded of course. The flying saucer will be plugged where the original tube went in to it as will the spot weld hole to make it air tight. The coupler will be welded on both sides as well to make it air tight and less chance of be coming loose. When I get it back from the welder I will weigh it against the weight of the stock pickup.
