Hi,
Sorry for taking so long -- I have been very busy.
Here is some info on the scrapers and windage trays...
Chevy straight six (230, 250, 292) crank scrapers (in Teflon if desired) and an option for a full length windage tray.
The tray is mounted to oil pan rail plates -- one is a modified crank scraper, of course. There are oil ejection ports underneath like on the factory Mopar slant six tray but these ports also have bevel edged inward facing louvers. The side rail has oil vents to allow oil draining down the side of the block to reach the pan and the tray has an angled strip of metal lying beneath this area. The strip serves two purposes -- one to guide the draining oil to the pan and another to act as a deflector to oil splashing laterally in the pan. At the rear of the tray there is a panel of thin Teflon that can be fitted tightly to the rear of the pan (it will flex upwards to improve the seal as well when the pan is installed). This is an oil surge baffle that prevents the oil from climbing the rear under acceleration. There is a movable block-off plate so that the tray can be used with oil pickup tube support struts that bolt to either the second or third main cap from the rear.
Many thanks to local Chevy drag racer Larry Page for lending me the blocks to construct the patterns!
Kind regards,
