EGR SYSTEMS: This manifold will not accept stock EGR (exhaust gas recirculation) equipment. EGR systems are used on some 1972 and later
model vehicles and only in some states. Check local laws for requirements. This manifold is a street legal replacement part when used with the OEM carburetor on 1968-72 472 and 500 c.i.d. V8 passenger cars.
• MANIFOLD: The Performer Cadillac is intended to be used in high performance and engine swap applications. The carb pad is 3″ taller than stock, and will not fit many stock applications. Check your hood clearance before installation! The manifold accepts either original equipment Q-Jet carburetors or Edelbrock Performer Series square-bore carbs as listed below. The runners and plenums are sized for operation from idle to 5500 rpm on 500 c.i.d. engines.
• CARBURETOR RECOMMENDATIONS: CAUTION- Use only carburetors recommended. If parts required for installation are unavailable locally, contact Edelbrock directly.
BRACKETS
Due to the design and leg configuration of the Edelbrock manifold, the stock air conditioning compressor and bracket will not fit. The mounting bosses are cast into the manifold only to facilitate fabrication of bracketry, if desired.
• GASKETS AND SEALANT
CAUTION: Do not use soft competition type intake gaskets for street applications, as deterioration and internal leakage may occur. Do not use Fel-Pro Permatorque (blue) gaskets, as they have insufficient “crushability ” for use with aluminum manifolds.
1. Use only Fel-Pro valley pan gasket set #MS 96028 or OE equivalent when installing the Performer Cadillac for street applications.
2. Apply Edelbrock Gasgacinch, #9300, sealant to both sides of the manifold as well as head surfaces. This procedure ensures a good seal.
3. We advise eliminating the end seals. Use RTV silicone instead. Apply a bead of sealant approximately 1/4″ high across the block end seal surface, overlapping the intake gasket at the four corners. This procedure eliminates end seal slippage.
