Running and Racing Reliably Part II: Continuing At The Bottom
The pump was installed with the bolts finger tight in the block because the factory bolt shoulders are not wide enough for interference fit through the pump body. Using this to his advantage, Jim positions the pump to provide a straight shot from the gear rotor in the pump to the bottom of the distributor. The bolts are tightened to 30 lbs.-ft. With the pump installed, you can see the Nunzi pump drive. Note that the collar completely surrounds the tang on the pump unlike the factory piece and other aftermarket replacements. Also, the Nunzi piece is made from better materials than typical replacement drives. View Related Article
