What makes a camshaft choppy?
LSA (lobe separation angle) determines the choppiness, it has to do with the overlap of when both valves are open, as in when the exhaust valve is closing and the intake valve is opening to pull fresh fuel in on the intake stroke after pushing out the burnt fuel.
Does a bigger cam give more power?
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.
What is a good camshaft duration?
Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam’s power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
What year did GM start using roller lifters?

How much preload does a hydraulic lifter need?
Hydraulic lifters use what is called lifter preload, which compresses the small piston inside the lifter a given distance. This preload compensates for growth so no lash is necessary. Stock factory preload specs are generally ¾ to 1 full turn of preload, which moves the small piston in the lifter roughly 0.050-inch.
Do you have to adjust hydraulic roller lifters?
One of the advantages of hydraulic lifters is they don’t normally require adjustment other than the initial installation. However, there may be situations where the valvetrain is partially disassembled, during the installation of roller rocker arms as an example, which will require adjusting the lifters.
Why do cammed engines lope?
Again, keeping all else constant, more duration will make the engine less efficient at low rpm, with more overlap dilution of the induction charge, and the later intake valve closing reducing the trapping efficiency. Therefore, a long-duration cam will cause rough running at idle (lope) and a loss of low-rpm torque.
What does an oversized cam do?
A bigger cam will open the intake valve wider, allowing more fuel and air into the cylinder. The larger the cam, the more fuel that is let in.
