Windage tray

[Tom Goldman]

I use a Moroso 21604 pan on my BBC which is very similar to the 20370 that is popular on a lot of SS big block Chevy's .
I have two versions of this pan ,one with the diamond screen and an earlier one with a louvered tray.......On the same engine with no other changes the louvered tray pan is good for a solid .070 ET and over 1 mph more. This was realized when I took the louvered pan off my spare engine at a race to replace the damaged pan on my engine in the car.
Ishihara -Johnson http://www.crank-scrapers.com/ is the company in Florida that manufacturers scrapers and trays for just about any engine....I found quite a bit of HP on my AMC Stocker using their stuff.

Tom, was the louvered tray from crankscrapers or was it a Mororso? What rpm range were you in? I've been told that my 7200 rpm's aren't enough to take advantage of a scraper and probably not enough to warrant a tray of any type.

Reher-Morrison Racing Engines

New! BBC Moroso Steel Oil Pan #21049
This BBC Steel oil pan is the best we have seen in all our years of building engines.
http://rehermorrison.com/product/wet-sump-system/

On the dyno, it has shown increased horsepower and steady oil pressure throughout the entire RPM range. This BBC Steel oil pan features a built-in windage tray. It is better at controlling windage, but still fits in dragsters and door slammers. To experience the full benefits of this oil pan, it should be used with the new Moroso oil pump (#22187) and pickup. We offer a combo of the pan and the pump with the pickup. To save time and money, you can also buy the complete wet sump kit featuring this excellent oil pan. See our wet sump section for more information.
