By chance, do you show these to Canton or let them know what you are doing?
I notice pretty regular interest in a windage tray in the FB Group. If one was available, it would sell but maybe not at a volume that would be feasible for them.
When I was measuring before building my windage tray, I realized that at least smaller stroke increases don't really change much with the rotating assy clearance requirements. While the stroke is longer, the rod big ends are smaller and the cap bolts fit closer to the rod than the studs on oem rods. This was convenient because I was able to use a spare 292 on a stand to work out the details and the confirm that no issues arose by installing it on the engine in the truck.
I got the windage tray screen and some 3/4" mandrel bent tubing sections for an oil pickup from Canton. They are pretty good to deal with.
