• 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 or RPM Air-Gap manifolds.
Generally speaking, the stock jetting for a Performer Series 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: The 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 (#2167 for 429/460 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 (#7167 for 429/460 c.i.d. engines) for use with Performer RPM series
manifolds (see catalog for details). Header primary tube diameter should be 1-7/8"-2”.
