LOS ANGELES - BLP Products, Inc. now offers a new option to the billet base plate they manufacture for the Holley 4150 series carburetors. The base plates can be ordered with Cylindrical Roller Bearings for the throttle shafts. At idle and part throttle, high vacuum occurs at the throttle shafts which can draw dirt into the carburetor causing premature wear to the throttle shafts and engine parts. A seal on each side of the bearing is designed to prevent dirt from entering the carburetor. The throttle bores are machined within .0002 inches. Base plates with installed bearings are available for 650, 750, 850, 950, and 1000 CFM carburetors. For more information, visit www.blp.com.
