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).

This cam will work fine with a stock converter. 12-676-4 may work with a stock converter but it is best with a 2000 stall. Both of these are solid lifter camshafts.

Speedway Small Block Chevy Solid Lifters
(Part #180651080)
                        Any time you put in a new cam, you must use new lifters! 

Mechanical lifters feature precision ground bodies for long life and durability. For engines that require top end oiling through the lifter.

Our lifters feature precise oil metering to ensure proper lubrication of the rocker arms and related components, while eliminating excess oil to the rest of the valve train. All 1955-86 Chevy V8. Set of 16.

COMP Cams 159-12 Engine Break-In Lube Oil Additive
(Part #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.
