Some engine swaps and racing applications do not need the heater, but it is tough to block off with the 7.3-liter Godzilla engine. The factory rear hose port is retained with a bolt (and the port is not tapped). This kit includes a zinc-plated steel plug with an o-ring seal retained by a bracket and bolt.
Holley Rear Block Plug Kit - Ford Godzilla Engine - 97-426
$20.98
Features:
- Elimination of the heater is difficult on the 7.3-liter Godzilla engine since the hose inlet and outlet passages are tough to plug & look cobbled up using traditional hoses, clamps, and plugs
- Machined steel billet plug with o-ring seal, mounting bracket, and retaining bolt – blocks off the rear port
- Works with 97-425 (front/heater block-off kit) to block all cooling ports
- The plug is designed to handle high pressure & high temperature – 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
- Ideal for use in engine swaps or racing applications that do not require a heater
