I've used crank scrapers in my bracket cars, Dart IHRA Stocker with an 8 qt. Milodon pan (with 5 qts.) and have one in my NHRA Aspen Stocker with an OEM style baffled Milodon pan.

I haven't been able to do any back-to-back comparisons, but from everything I've heard, read and just visualizing how everything works, a scraper helps.

They usually need some fitting to the counterweights & rods. Extra care is needed to make sure the front and rear pan rails seal because the scrapers are usually sandwiched between the block & pan rails. That drops the pan a bit. But I just add extra silicone on the outside, especially at the front & rear seals. Oil pan studs make things a bit more convenient, with or without a scraper.

I use a stock volume and pressure oil pump as well.
