crank scraper question

With your wealth of knowledge, I'm truly surprised about you not knowing about scrapers, aka windage trays. They sit just below the crankshaft. It's a perforated piece of sheet metal to prevent the whipped up froth of oil at high RPM from causing oil starvation to the oil pump. I believe all 340's came with one from the factory. My 1970 Swinger 340 has the factory part. Not trying to belittle you, but I can send you pics or more information, as can smarter members on my favorite site.
They did. Also, some of the HP 360s did as well. I won't say all, because I think that's been disproven, but a lot of them did. Like some of the E58s and such. IMO though, I believe a decent oil pan baffle is every bit as good as a windage tray.......now throw in a crank scraper and things go to the benefit of that.
