Tappet Block And Powerglide Tappet Kit. Polished

JIM’S, tappet block and Powerglide tappet kit. Polished

Details

This kit has a 3/8″ lower seat for the pushrods, reducing the pushrod to tappet angle. Includes a set of two 7075-T651 polished billet tappet blocks and a set of 4 large bore Powerglide big axle tappets. The tappets are special extra wide .761″ outside diameter JIM’S Powerglide tappets. Therefore OEM .731″ diameter Powerglide Shovel tappets are not interchangeable. Note: 53-E76 Pan & Shovel models will require a tappet guide bolt conversion kit, like 502990 Allen / 989173 Cap style / 513555 Acorn, that is correctly threaded for 53-E76 crankcases, so the bolt head will fit the flat L76-84 design of these JIM’S tappet guides.
