IMPORTANT A/B MEASUREMENTS
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. The heights of all Edelbrock manifolds can be seen on the installation notes tab on product pages.
Please Note: To figure carburetor pad height, add dimensions "A" + "B" and divide by 2.
For example: carburetor pad height of Performer manifold #2101: (A) 3.5" + (B) 4.6" ÷ 2 = 4.05" pad heigh
