AUTOMATIC TRANSMISSION CHECK
For best performance, economy, and emissions, the shift point must be checked before and after the manifold change.
NOTE:
This check should be performed ONLY at a sanctioned drag strip or test track.
With the shifter in Drive, accelerate to wide open throttle from a standing start. Hold in this position, noting speedometer MPH when
the transmission makes the first 1-2 shift. After the Pro-Flo system has been installed, make the same test, again noting MPH of
this first shift.
The transmissions on certain vehicles require precise adjustments. We recommend that you consult a reputable transmission shop
for final adjustments once the Pro-Flo system has been installed. Incorrect shift points can result in transmission damage.
ENGINE CLEANING
Edelbrock recommends that the Pro-Flo system be installed on a clean engine in order to prevent dirt from falling into the engine
lifter valley or intake ports.
1.
Cover ignition. Use engine de-greaser and a brush to thoroughly clean the manifold and the area between the manifold and
valve covers.
2.
Rinse with water and blow dry.
EXHAUST MANIFOLD HEAT RISER VALVE & AIR INJECTION TUBES
If your vehicle is equipped with an exhaust manifold heat riser valve (typically located on the passenger side of the vehicle below the
exhaust manifold), remove the valve for proper operation. If applicable, any air injection tubes must be removed and holes in the
exhaust manifold plugged for proper operation.
HEADERS
For best performance, headers are highly recommended. The remainder of the exhaust system should be free flowing, preferably a
dual exhaust system using low back pressure mufflers.
COOLING SYSTEM
The minimum requirements for the thermostat are 180° but the ideal thermostat is 195°. When the vehicle is at 175 or below,
system will stay in cold start mode and not perform properly.
