Larry, I think the semi-circular tray actually works more like a wiper than a screen type, in a space that doesn't give ya much.
I did have a Milodon or Summers Bros. semi-circular expanded metal windage tray that worked well with a dragster pan and wiper. It was vintage mid '80's , haven't seen one like it lately. It got hurt I think. I've been using a B&B pan on my bracket ride that has a side "catch/wiper" that could be adapted in a stocker pan, with a trapped sump, but I don't feel it is as effective as the Z-28 setup I used to run. With the B&B, 1/2 quart of oil in the pan from 6 1/2 to 7 costs me .04 in E.T., indicating without further investigation that the B&B pan isn't great without the semi-circular tray which I did run with it for a while. I don't gain ET as the B&B gets to 6 quarts or under, it's just that 1/2 that brings it to full that gets me. The Corvette tray is flat and not as close.

I started using pan rail mounted crank scrapers on my engines this year. Using studs for the oil pan helps assembly and alignment. I wasn't able to do any back-to-back comparisons, but the design appears to be beneficial. They have scrapers as well as windage screens for most engines, including small block Chevy.

While in oil pan mode with my LT1, I fooled around (key word here being "fool") with scrapers and learned that a pan rail scraper that has no kickout into which oil can be scraped is pretty ineffective. It makes a lot more sense to put the scraper in the lower side or bottom of the pan so the oil has a place to go. The Corvette has a lot more room in the front of the pan so there is room for a full length scraper and screen; not sure what the F-body guys should do but as I understand the current rules; crossmembers can be modified to allow pan removal so that opens a window for a more desireable OE pan. By the way, Alan is correct about "welding" on stocker pans; not legal! I had Stef's do a couple of pans for me; pretty good quality, nothing visable from the outside, reasonable price, seem to work well. I think that the oil pan is a good place to look for parasitic HP losses but within the confines of a stock pan, you run out of options pretty fast.

If your application is for I.H.R.A. Crate Motor ? Then any aftermarket oil pan can be used.Modification to the sump area only.No side kickout.B&B worked for me.Seven quart pan with 5 quarts in picked up,but pressure fluctuates under braking.Five and a half in solved that.
