The Edelbrock 1-inch 4-hole phenolic carb spacer #8711 features a four-hole design intended to enhance low-rpm torque and throttle response while helping to dampen reversion effects on the carburetor. Made of black phenolic plastic and one inch thick, it increases carb-to-plenum distance and is used where improved low-end drivability and reduced reversion are priorities.
