JIMS, tappet block and Powerglide tappet kit. Chrome
This kit has a 3/8" lower seat for the pushrods, reducing the pushrod to tappet angle. Includes a set of two 7075-T651 chrome plated billet tappet blocks and a set of 4 large bore Powerglide big axle tappets. The tappets are special extra wide .761" outside diameter JIMS 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 JIMS tappet guides.
