CAMSHAFT AND HEADERS: The CH-6B intake manifold is compatible with aftermarket camshafts and headers designed to work in the 2500-
6500 rpm range, such as our Performer RPM #7194 (1500-6500 rpm) for 383-440 c.i.d. engines (see catalog for details). Header primary tube
diameter should be 1-7/8" depending on the specific engine combination.

PREP AND TUNING FOR POWER:
NOTE: Please refer to Edelbrock Performer Series Carburetor Owner’s Manual for detailed tuning procedures.
1.
Due to design, the fuel/air mixture and cylinder charging are very efficient with the CH-6B intake manifold. Generally speaking, the stock
jetting for the recommended aftermarket carburetors will not need changing. Specific applications may show an increase in performance
through further tuning.
2.
Aftermarket distributor curve kits may be used with this intake manifold.
3.
Use modified or high performance cylinder heads such as our Performer RPM.
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 may lean carburetor calibration. Should this occur, recalibrate with a richer jet.
