Installation Notes
    • Manifold height: A-4.20", B-5.25" (.70" taller than #2101)
    • Carb pad height: 4.27"
    • Carb recommendations: Edelbrock #1409 or #1410
    • Port exit dimensions: 1.16" x 1.92"
    • Recommended intake gasket: Edelbrock #7201
    • Use RTV sealant to properly seal end seals, such as Edelbrock High Temp Silicone sealant #1076
    • DO NOT USE END SEALS GASKETS
    • Use #8504 Edelbrock bolt kit
    • Sealant must be used on intake bolt threads if the threads extend into lifter valley or coolant passage.
    • NPT/Pipe thread fittings require the use of Teflon tape or paste on threads to ensure a proper seal.
    • DO NOT OVERTIGHTEN NPT/Pipe fittings, this may cause the aluminum to crack around the fitting boss. NPT/Pipe thread is a tapered thread.
    • Hardened washers Must be used with intake bolts to ensure proper torque and prevent galling of the aluminum.
    • Edelbrock does not recommend the use of an economy-type carburetor such as the Performer series #1406 or #1411 on Performer RPM Intake Manifolds. Economy type carburetors are calibrated lean for fuel economy and will not perform properly on this style of intake.
    • A carb flange and plenum design that works well with spread-bore (Q-Jet) or square-bore carburetors without the need for adaptors.
    • Has provision for exhaust heated divorced choke for Q-Jet Carbs.
    • Use Edelbrock rod #9172 for divorced choke with Q-Jet.
    • Proper installation is the responsibility of the installer. Improper installation will void your warranty and may result in poor performance and engine or vehicle damage.
