Q & A

What's in the Box

There are many things that effect vacuum. Camshaft lobe separation, lifter style, intake manifold, piston rings, compression ratio and overall valve and engine condition. Due to many and varied engine combinations, Speedway Motors offers no warranty on camshaft and or lifters for either performance, vacuum or longevity.

Must be used with break-in oil additive (sold separately).

Rhoads Lifters 8178 Chevy Hydraulic Lifters
SKU-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.

COMP Cams 159-12 Engine Break-In Lube Oil Additive
SKU-282159
                        

ZDDP-enhanced Engine Break-In Lube Oil Additive from COMP Cams provides maximum engine life while also allowing it to reach its full performance potential. It does so by improving the surface mating of valve train components (especially flat tappets), rotating assembly, rod journals, piston rings, valve guides and other vital areas of the engine. This proprietary break-in lube formula includes the optimum amount of critical additives ZDDP (Zinc & Phosphorus), Molybdenum, detergents and high grade base oil.

The multi-viscosity, mineral-based COMP Cams Engine Break-In Oil Additive is fully-formulated and requires no additives or supplements. In addition, the oil is fully compatible with gasoline, methanol and high octane racing fuels.
