INSTALLATION INSTRUCTIONS
1) Use only recommended intake gaskets set when installing this intake manifold.
2) Fully clean the cylinder head intake flanges and the engine block end seal surfaces.
3) Use a factory style valley pan along with the recommended gaskets.
4. Apply Edelbrock Gasgacinch sealant P/N 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and
attach the intake gaskets.
5) Install the intake manifold and hold-down bolts. Torque all of the manifold bolts in two steps by the sequence shown in Figure 1 to 25 ft/lbs.

PREP AND TUNING FOR POWER:
NOTE: Local emission laws must be checked for legality of any carburetor or ignition changes.
Performer Series Intake Manifolds
1. The long equal length runners in the Performer manifold create a very strong signal to the carburetor. In some applications, the stock
rods or jets may need changing for best overall performance. Refer to your carburetor owner's manual for details.
2) Performer manifolds deliver excellent drivability and power utilizing stock distributor settings. Some applications may benefit from
resetting the initial advance ±2° from the factory specification.
3) Aftermarket ignitions and more aggressive advance curves may be used with Performer packages.
4) Installation of aftermarket headers or camshafts may lean the carburetor calibration. Should this occur recalibrate with a richer jet.
Performer RPM Series Intake Manifolds
1. Due to design, the fuel / air mixture and cylinder charging are very efficient with Performer RPM manifolds. Generally speaking, the stock
jetting for a Performer or Thunder Series carburetor will not need changing. Specific applications may show an increase in power by
tuning the fuel mixture.
2. Aftermarket distributor curve kits may be used with Performer RPM series manifolds.
3. Use modified or high performance cylinder heads such as our Performer RPM, and port-match the manifold to the heads.
4. The compression ratio should be at least 9.5 to 1 to work properly with Performer RPM camshafts.
5. Installation of aftermarket headers, camshafts or both with an Edelbrock Performer RPM series manifold may lean carburetor calibration.
Should this condition occur, recalibrate with a richer jet.

CAMSHAFT AND HEADERS: Performer Series manifolds are compatible with aftermarket camshafts and headers designed to work in the
idle-5500 rpm range. Edelbrock has developed a dyno-matched, street proven camshaft (#2192 for 383-440 c.i.d. engines) for use with
Performer Series intake manifolds. Header primary tube diameter should be 1-3/4". Performer RPM Series manifolds are compatible with
aftermarket camshafts and headers designed to work in the 1500-6500 rpm range. Edelbrock has developed a dyno-matched, street proven
camshaft (#7194 for 383-440 c.i.d. engines) for use with Performer RPM manifolds (see catalog for details). Header primary tube diameter
should be 1-7/8".
