Where did you get that scraper? I have been watching episodes of engine masters finding power in windage control. They found 8 hp in a windage tray, but found 22hp in a custom Moroso pan. The pan had kick outs close to the rail. The extra power is found over 5500rpm. I would be interested in a scraper for sure, the windage tray i will have to give that more thought as my 572 is not an all out max hp deal. This is also the same company people are saying they didn’t get their stuff. I know I ordered mine and it didn’t show up when he said. I called atleast once or maybe twice additionally before I got it. I ordered mine in 2016  I'm regularly in contact via email, sometimes I get a reply, sometimes I don't. I haven't been able to catch him on the phone but have spoke to his wife who said he would return my call..... it didn't happen.
