I have run windage trays on my small blocks and found no big differences. But for the low RPM cop cars the tests were positive. My LRT had one. On the 5.2L or 5.9L Dakota oil pans, 4 qt, there is no room as the pans are shallower, closer to the crank. I don't think you could, or should, run a stock Dak/Durango pan on a 4" or 4.125" stroker crank.

I bought the $110 Crank Scraper kit from Ishihara Johnson (crank-scrapers.com) for my 4 inch stroker 5.9 410. It is a bear to fit. You must fit it to the crank and block. The oil pan bolt holes are undersize. The stand offs for the main caps do not line up. The dip stick hole is way off. Then you must seal it to the block and pan as it is thick and will leave a gap at the front timing cover and rear main cap.
