What a crank-scraper is and other technical info... Some comments on our products...

We will try to keep this list updated but if you do not see your engine listed here please ask!  We can  do custom stroker or knife-edge crank designs.  We can provide templates for initial fitting and adjustment. Templates cost $100 and are a separate charge from the scraper pattern chosen.

We have included some representative pictures of the scrapers we make.  If you would like to see a picture of a particular scraper please ask -- we would be more than happy to send one through.

When available (please enquire) our zero-clearance Teflon® scrapers run an additional $130.00 to the cost of the standard steel scraper unless noted.

Remember, your vehicle may have an engine made by a different manufacturer so check both product lines.  If you are still unsure, please contact us.

Chevy straight six (230, 250, 292) crank scrapers (in Teflon® if desired) and an option for a full length windage tray.

Scraper alone: $94.95; scraper with windage tray: $504.95; Teflon® option on either: add $130

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!
