Ford Racing Performance Parts Boss Engine Block For Project Stolen Goods - Major Management Muscle
|
The R302 block has screw-in galley plugs for oil but press-in plugs for the water. Dart blocks use press-in freeze plugs as well, unless machined by the builder for the screw-in-type pieces. The Boss 302 sets the standard with screw-in freeze and oil-galley plugs. The screw-in type of plugs adds more structural rigidity to the block and won't pop out in high-horsepower/high-stress applications. View Related Article
