JIMS, blok popychaczy i zestaw popychaczy Powerglide. Chrom

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.
