Q & A

What's in the Box

High Energy Hydraulic lifters have a patented constant orifice metering valve that precisely meters oil to the rocker arms. Continuous contact between the metering valve and pushrod seat is maintained, eliminating excessive oiling at high engine speeds. The pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength and wear resistance.

In addition, High Energy Lifters have a lightweight check valve disc that allows for quicker response, which results in increased engine speed before valve float. This check valve disc also maintains added control at all engine speeds and loads.

COMP Cams High Energy Hydraulic Lifters also contain a longer piston than conventional hydraulic lifters, which provides more load bearing surface and increases lifter longevity.

why would a hydraulic lifter freeze up, yet they come apart easily and have oil in them Engine ran fine week before, and then would not get over 5000rpm. Lifters appear locked up. Would get up to 7200rpm before no problem.

If the internals of a hydraulic lifter are not working correctly it could either lock up at the top of its travel and hold the valve open or it could also fully compress an not allow full lift to be presented to the valve.

Rhoads Lifters 8178 Chevy Hydraulic Lifters
(Part #6118178)
                        It's not uncommon to pick up 2-3" of vacuum under 1500 RPM just by using these lifters. Normally see 25% or more increase in low-end horsepower for performance hydraulic cams.

Lifters bleed down slightly at idle and lower RPM, causing a reduction in valve duration of approximately 10° to 15°, and reducing valve lift .020" to .030" at idle.

Set of 16.  All 1955-86 Chevy V8.

Rhoads Lifters 8178X V-Max Chevy Lifters
(Part #6118178X)

Rhoads V-Max lifters increase low-end torque and engine vacuum up to 50% more than original Rhoads lifters. They also rev higher, making them ideal for racing classes with vacuum rules. V-Max lifters are fully adjustable and require an adjustable valvetrain.

Typical vacuum increases range between 3 to 5 inches at idle when used with bigger cams. Duration is reduced between 5 and 20 degrees at .050" lift depending on the adjustment. As the rpm increases, so does the lift and duration. Full restoration takes place at approximately 4000 rpm.
