All camshaft are not adaptable or adjustable for 5.3 Vortec, whereas some tuners are mainly manufactured for it. You have to understand the model of the vehicle and then finding for the best-suited camshaft. So some things should consider before purchasing a camshaft-
Ensure the gathered information you need is right. Source
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.
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.
216/222 cam is the most prominent cam for 5.3, stock exhaust cats, stock converter, Idles with a little lope that provides 40hp and 20 tq in second gear pulls.
The Stage 3 LS1 cam is the largest cam that can be recommended with the stock torque’s converter. It can use with the stock rear gears, stock intake manifolds, stock exhaust manifolds, stock torque converters.
However, a stage 3 cam motion hydraulic roller cam provides extended RPM capabilities, excellent low-end torque, and mild performance idle over the stock camshaft. A performance replacement requires more power without low gas mileage implicated with the larger cams for functioning correctly.
How do I get more power out of my 5.3 Silverado?
For getting more power to 5.3 Silverado, the basics should install for starting transforming the Vortec Engine of 5.3 liter that improves power as well as an exhaust system a high flow cat-back should install.
1. The stock air filter replacement with the aftermarket air. 2. Performance Spark Plugs, Filter, and Wires increase the power of gapping and improves efficiency. 3. An aftermarket air filter allows for getting improved air into the engine and getting out of thin air. 4. A series of computer chips helps to run electronic engines and control functions.
You can daily drive a cammed truck without any problem. It depends on the cam, and you will need a Trans cooler and a stall converter. In the meantime, you will also need a computer tune. But you have to ensure no junk and to buy the right parts.
This article has thoroughly explained almost all the advanced features, specifications, and benefits of the best cam for 5.3 Vortec. You may have gained knowledge about the different cam and already understood which one is the best suited for your vehicle among them.
