CHECKING FOR HOOD CLEARANCE
To ensure adequate hood clearance, check the height of your stock manifold and compare the "A" and "B" measurements against those of the Edelbrock manifold prior to purchase. Please Note: To figure carburetor pad height, add dimensions "A" + "B" and divide by 2.
For example, Performer RPM Manifold #71014:
(A) 4.20" + (B) 5.25" 2 = 4.725"
