Installation Notes
  • Manifold ht: 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: GM # 10159409
  • 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 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.
  • Will not fit under stock Corvette hood.
  • 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 rod # 9172 for divorced choke with Q-Jet.
  • Even though manifolds are compatible with EGR systems, this does not mean they are legal for use on emissions controlled vehicles. Check local laws for legality.
  • 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.
