PREP AND TUNING FOR POWER:
1.
Due to design, the fuel / air mixture and cylinder charging is very efficient with the RPM Air-Gap manifold. 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.
4.
The compression ratio should be at least 9.5 to 1 to work properly with most camshafts designed for use in the 1500-6500 rpm range.
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 RPM Series manifolds are compatible with aftermarket camshafts and headers designed to work in the
1500-6500 rpm range. Header primary tube diameter should be 1-3/4".
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.
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.
4.
Dowel Pin Removal: Remove the dowel pins from the front and rear valley gasket surfaces of the engine block. Use Vise Grips, or a
dowel pin puller, etc., to remove the pins.
5.
Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼" high bead across each block end seal surface,
overlapping the intake gasket at the four corners. This method will eliminate end seal slippage.
6.
Install the intake manifold and hold-down bolts. Torque all manifold bolts in two steps by the sequence shown in Figure 1 to 12 ft/lbs.
