What is a Stage 3 cam?

The Stage 3 cam is designed to work with some larger valves, port work, and upgraded carburetor or EFI system. This cam starts moving the power band a little higher in the RPM range (2500-6000). This is the biggest cam we recommend for a street application. It is used commonly in the race and hot street applications.

How much HP does a Stage 3 cam add?

See all 17 photos With the stock intake manifold back on, power improvements were also very strong, with 592.2 hp and 471.9 lb-ft of torque, a gain of 39.9 hp, putting the 2018 cam upgrade on par with first- and second-generation Coyote cams.

What does stage cam mean?

Stage 1 cam sets are used to give increased Torque output in the RPM range below the engine’s Torque peak. Stage 2 cam sets are used to provide more power. If you want to ride situations with higher average speeds, these cams are for you.

The BTR Stage 3 N/A Camshaft (LS1/LS2/LS6) is the go to for people desiring an aggresive idle matched with a powerband that will stretch into the 450+ whp range around 6000 RPM when paired with quality supporting modifications.

How much HP can a cammed 5.3 make?

After installation of the cam, the 5.3L responded with peak power numbers of 467 hp at 6,600 rpm and 418 lb-ft of torque at 4,900 rpm. With no other changes, the cam swap improved the peak power output by 108 hp, with even greater gains coming at higher engine speeds.

Most Stage 1 type modifications are typically in the +10-15% power increase over stock. Stage 2: this is typically referred to an engine with a performance cam upgrade as well as the other components within a Stage 1 combination. A typical Stage 2 has generally +20-25% more HP than stock.

How do I know what stage cam I have?

How to Identify a Camshaft by Number
Find the model prefix. The model prefix is the first part of the camshaft number, and it describes the vehicle that the camshaft is meant for. Find the profile or grind number. This number should be on your camshaft, followed by a number of degrees.

What kind of camshaft is best?

Cams with durations in the 195 to 210 degree range (measured at . 050˝ cam lift) are usually considered best for stock unmodified engines and those with computerized engine controls. Once you go beyond 210 to 220 degrees of duration, intake vacuum starts to drop.

Performance cams increase the duration and timing of the valve openings during the engine stroke, increasing horsepower and making your car accelerate more quickly. You’ll idle slightly rougher with a performance cam, but get a throaty rumble that’s desirable for some gearheads, depending on your vehicle.

How can I make my 5.3 faster?

Install the basics to begin transforming the 5.3-liter Vortec engine. A high-flow cold air intake is the most basic modification necessary to increase the speed of these engines.Install a high-flow cat-back exhaust system.
