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 plastic templates for initial fitting and adjustment.

 

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 TeflonŽ scrapers run an additional $100.00 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.

D-series

Independent dyno testing of the original D16 scraper by Church's in L.A. showed a 1.5 % to 3 % increase in hp depending on RPM.  Many people thought that the massive girdle structure present on the D-series engines would make scrapers redundant -- this is not the case!

Our D15/D16 design attaches along the girdle and does not interfere with the closing of the aluminum or steel pans used on these engines.  See photos of D16Y8:

 

These D15/D16 scrapers are also available in TeflonŽ.  The TeflonŽ framework does require slight adjustments for clearance in the cast aluminum sump.

Note that we now include a thin version of our original pan rail mounted design so that the D-series engines can have the benefits of a dual scraper that operates on both the downstroke and upstroke of the engine.

$74.95 for the steel dual scraper set and $174.95 for the set with the TeflonŽ bladed downstroke scraper.

D series windage tray option

The windage tray option includes the dual scraper set as well as directional screening around both sides of each bay on both sides of the girdle.

The windage tray shown below has a TeflonŽ bladed scraper; the exact screening designs will vary depending on what engine and pan combination you will be using. 

$299.95 (steel scraper version); $399.95 (TeflonŽ scraper version)
