Aftermarket Camshafts (a.k.a Cams) are a great way to take full advantage of all the performance mods you’ve made to your 5.0L Coyote Mustang.

You may see a 10-15 horsepower gain by swapping the cam, which isn’t bad, but it can be made up for in so many different ways.

B303 states it provides significant HP gains above 4000 RPM (OK what is happening below that, since it also states it has good low-end torque. E303 states it provides significant HP gains above 2500 RPM, with same statement regarding good low-end torque.

Registered. You can’t swap just the cam and nothing else. Not counting the fact that sticking in a big cam in a stock engine and it running worse due to a mismatch with cylinder head and intake airflow, at the very least you MUST swap the springs.

Registered. Just cams and degree without changing springs $600. Cams, degree, springs $1000. That’ll about be the average.

Around here the shops charge around $2500 for parts and labor for an LS3 cam install.

Assuming you provide your own new camshaft, most shops will charge between $600 and $1,000 to cam your truck.

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.

So inline engines have two cams, and V engines have four. Usually, double overhead cams are used on engines with four or more valves per cylinder — a single camshaft simply cannot fit enough cam lobes to actuate all of those valves.

The rotor and housing of a rotary engine from a Mazda RX-7: These parts replace the pistons, cylinders, valves, connecting rods and camshafts found in piston engines. Like a piston engine, the rotary engine uses the pressure created when a combination of air and fuel is burned.
