PRP 2 Barrel Alum Carb Adapter w/Phenolic Top

Description

Aluminum base with phenolic top to dissipate heat better than all aluminum adapters. Vanes cut into the base for better airflow. Dyno proven results of up to 15 more horsepower over standard adapters. Fits Quadrajet and Holley 4bbl intakes.

  • Is this spacer made to be run with a single or dual plane intake? Also if ran on a dual plane does it isolate both sides of the intake from each other or does it have a crossover?
    This adapter can be used on both dual plane and single plane / open plenum intakes. There is no cross-over. If installed on a dual plane intake with a gasket that fits the intake perfectly with a divider piece in the middle of the gasket, both sides will be separate from one another. However, if a standard Holley style 4bbl open gasket is used there will be a gap between sides the thickness of the gasket used making somewhat of a “crossover” chamber.
  • What is the height of this adapter?
    The measurement from the bottom of the adapter to the top of the phenolic top is 7/8” and from the bottom of the adapter to the top of the stud is 1-7/8”.
