Holley Ford 7.3L Godzilla Rear Block Plug Kits

Some engine swaps and racing applications do not need the heater, but elimination of the heater is difficult on the 7.3-liter Godzilla engine since the hose inlet and outlet passages are tough to plug and look like a cobbled up mess using traditional hoses, clamps, and plugs. Holley Ford 7.3L Godzilla rear block plug kits include a machined steel billet plug with O-ring seal, mounting bracket, and retaining bolt to block off the rear port with a professional look. Features: * Works with Holley's front/heater block-off kit to block all cooling ports * The plug is designed to handle high pressure and high temperatures--typical conditions of the cooling system * Easy installation without the need to tap holes or fabricate special plugs and caps * Steel plug features a clear zinc-plated finish Show Less
