+ Large Image	GHP-4025	Crankshaft Scraper- The crankshaft scraper fits between the block and the oil pan gasket on the starter side of the engine. Helps "scrape" oil off of the crank and rods and return oil back to oil pan. Cuts down on oil aeration. Claimed to free up HP at higher RPM's. Easy to install! �� �Laser cut for a close �fit to stock rods and �crank counterweights on 400-430-455 engines. Because of factory tolerance variations or after market rods you may find it necessary to trim some of the areas for clearance. � Minimum recommended clearance is .030" from the crank counterweights and .060” from the rods. Remove any burrs after trimming. �� Rotate the engine 360� and check all areas for sufficient clearance. After thoroughly checking for clearance, cement the scraper to the block with a thin coat of black silicone and secure it to the block with the pan bolts. Let it set for at least an hour to cure. Put a small amount of silicone at the ends of the scraper and install the oil pan gasket and pan in a normal fashion.
