Flat Tappet vs. Roller

Flat tappet cam slide against the cam lobes and use a slightly curved bottom lifter, whereas roller cam is hardened steel cam and use lifters that roll over the cam lobes with a wheel or roller.

Hydraulic or Solid?

The hydraulic lifter is self-adjusting, but the solid lifter is not. Hydraulic uses a spring-loaded plunger, oil-damped to maintain valve lash, whereas mechanical lifter relies on adjustable valvetrain, adequately set up. Solid cam produces more power than hydraulic. Source

Note: Chrysler offered many size varieties of “stock” parts, so use measurements or numbers like 1600 RPM stall, not “stock stall”.

Cylinder pressure note:

Cylinder head material, the static compression ratio, the engine’s altitude, the engine’s closing point, the intake lobe, and the final displacement of the engine are responsible for cylinder pressure. Build the engine for 165psi cylinder pressure with iron heads while using 93 octane gasoline, and aluminum heads using 195 psi cylinder pressure. It is the maximum safe power and pressure without odd spark curves or detonation.

The static compression ratio must raise for maintaining the cylinder pressure so that the camshaft gets larger. For maximizing the engine’s power, request the computer-generated cylinder pressures while ordering the Real Chrysler Camshaft.

Mopar Performance camshaft note:

Replace a Hughes Engines “real” Chrysler a Mopar Performance camshaft through 5º to 7º smaller at .050″ tappet lift for improved power in all RPM ranges.

Besides the cylinder head flow, the flow in the RPM range in the engine and the intake-to-exhaust flow percentage is essential. A high percentage head can use more closely matched exhaust and intake lobe figures cam. In contrast, a low ratio head between the exhaust and intake flow can be benefited from more exhaust duration for evacuating the burned gases.

Lifts refer to the length of the raising valve from its seats in inches in the cylinder. Gross and lobes are common types of lift. A cam card refers to the stock ratio of engines, whereas gross lift alters by changing the rocker’s ratio, i.e., 1.5 to 1.6. a cam can slightly be upgraded without changing it.

The rocker ratio multiplies the lobe lift provides the valve lift number through a non-stock ratio.
