MANIFOLD & CARBURETOR HEIGHT VS. PRO-FLO HEIGHT
1. Remove air cleaner.
2. Lay a straightedge (such as a yardstick) across the top of the carburetor from
front to back.
3. Measure from block and manifold end seal surfaces to straightedge.
4. Record these measurements (height A and height B).
5. Add height A and height B and divide by two to get the average height.
6. The Pro-Flo manifold and air valve measures 7.55” at the (A) and 9.10” at the
rear (B).
9. Compare the two measurements. If the Pro-Flo unit is taller, subtract this
amount from the hood clearance figure to determine new hood clearance.
CAUTION: You must maintain at least 1/2-inch clearance between the hood and air
cleaner because of engine torque. If you have insufficient clearance, a low profile
air cleaner may solve the problem.
EMISSION CONTROLS
The Edelbrock Pro-Flo system will not accept stock emissions control systems. Check local laws for requirements before installing the Pro-Flo
system. Not legal on pollution-controlled motor vehicles.
DETERMINING HOOD CLEARANCE
NOTE: Check hood clearance before removing stock manifold.
1. Use modeling clay or putty to make five small cones, two or three inches high.
2. Position cones on air cleaner at front, rear, each side, and on center stud.
3. Close hood to locked position and re-open.
4. The height of the cones indicate the amount of clearance between the hood and the air cleaner. Record these measurements.
