What you may consider is isolating the camshaft by forming a closed tunnel with oil return run directly down to the pan. Cam, lifters and bearings see plenty of oil maybe too much but would not fall into windage with an internal or external oil return line or limit the fall to the rear only for not 100% effect.

When looking at this a few years ago it's difficult with SBC without a lot of work I spent hours cutting and filing PVC tube to fit planning to pin and epoxy but issues with connecting rod clearance made it too much work at that time and became evident sheet metal would have been a better choice.

When searching cases where I could see this actually done this was with a Ford with dry sump much easier to control putting oil in the front and return in the back the tunnel would be filled or nearly.
Great idea to apply to a stocker there would be HP there but the labor cost would be more than most would pay but a crafty guy doing it for himself............
