Ford 390 FE - Build A Low-Buck Street/Strip FE
|
Restricting oil to the rocker shafts in an FE head is a simple matter of dropping a drilled orifice into the oiling passage in the head. For the Edelbrock heads, you can spend $5 on a restrictor kit from Precision Oil Pumps or just take some 3/16 round brass stock and drill a 0.070-inch hole through the middle before dropping it into the oil hole. The rocker assemblies will still get plenty of oil, and more will be available for the mains and rods. View Related Article
