Holley Accelerator Pump Cams
Holley accelerator pump cams will allow you to "tailor" accelerator pump performance to your engine's actual requirements. They include cams that have a different shape or profile to give different results. Cam "lift" directly affects the accelerator pump stroke, and, therefore, pump capacity. Ramp profile or shape controls the "timing" of the shot. A steeply-rising ramp shape will give a fast, heavy fuel shot right off idle. Conversely, a gently sloping ramp will spread the pump action over a longer period of time.

Holley Carburetor Float Kits
Holley carburetor float kits work with side-hung and center-hung Demon and aftermarket Holley carburetor floats, as well as many OE Holley, Ford, Chrysler, GM, Motorcraft, AMC, and Rochester marine carburetors. Offered in brass and Nitrophyl for internally and externally adjustable floats, they're available as primary floats, secondary floats, and secondary floats with notches that include jet extensions. Holley's wedged floats feature a reinforced float bracket assembly that allows more fuel to flow through the bracket—especially when using bottom-feed needles and seats. Technical notes for Holley carburetor float kits: * Wedged floats are designed for oval track use, so the float stays open in turns * The use of brass floats on the secondary side of Model 4160 carburetors factory-equipped with Nitrophyl floats may result in loss of fuel control and flooding if the floats contact the metering plate * You should only install jet extensions and notched floats in rear fuel bowls

Holley Sniper MAP Sensors
The pressure inside the intake manifold is an extremely important input to the engine control unit. Holley Sniper MAP sensors respond to changes in manifold pressures and relay the information to the ECU in the form of a voltage signal ranging from 1-5 volts. These replacement sensors will handle applications up to 25 lbs. of boost. Additional notes: * Utilizes stock attaching points * Sensor monitors manifold vacuum, varying output voltage to the ECU as a function of load placed on the engine—providing necessary data to control fuel enrichment

Holley Replacement Power Valves
Holley replacement power valves are an important component in the power enrichment circuit of Holley's performance carburetors. They operate by using engine vacuum to control their opening and closing rate. When they open, additional fuel is supplied to the main system during heavy load or under full power situations to eliminate hesitation and bogging--ensuring the smooth delivery of power without any drivability concerns. They're available in many different vacuum ranges to time the system's operation to your specific requirements, and they come in your choice of single-stage, two-stage, and high-flow designs. A gasket is included.
