Typically, it will exceed 12:1. Fuel management/tuning are very critical to reduce detonation and the risk of heat damage. Higher compression shortens the engine's life. Because this cam only functions well at higher RPMs, the other cam specifications can take advantage of this and be optimized for more power.
Camshaft: Definition, Parts and Function with [Diagram

A camshaft is used to open or close the engine valve for the right timing. A crankshaft is employed to convert the reciprocating or oscillating motion of the piston into rotary motion. The camshaft is rotated by the timing belt and is attached to the crankshaft. The crankshaft is rotated with the help of a piston.

The camshaft is the command center of the engine. It controls the intake and the exhaust events and plays a major role in the power-making process. Flat-tappet cams are used in some racing series, but roller cams are the prevailing camshaft type in most professional series.

288 and 298 degree cams are considered to be “Racing cams” and are used on cars that need to rev a lot higher than your average street car. Performance camshaft manufacturers like STK enterprises can offer you great advice when you are ready to buy a cam. We would advise to speak to a trusted cam manufacturer about the performance you require …

Camshaft duration is the amount of crankshaft rotation that occurs as the cam lobe moves the lifter off of the base circle; it is measured in crankshaft degrees to make it easier to degree (check) the cam to make sure it is positioned properly in the engine. Determining the specific point that the lobe begins to move, the lifter off of the base circle (upwards) can be difficult--so …
TECH QUICKIE: What is a '3/4 Race' Camshaft? - EngineLabs

The original 3/4 race cams are the forerunners of today’s street-performance grinds. The term likely originated in the ‘50s as the burgeoning hot-rod industry was modifying Ford Flatheads to drag race on airport runways and attempt top-speed runs on dry lake beds. The legendary Ed Winfield was one the early pioneers in grinding camshafts ...
Advancing / Retarding a Camshaft - Summit Racing …

A Basic Overview of Cam Timing. To advance or retard a camshaft is to change the alignment between the camshaft and the crankshaft. When a cam is installed "straight-up," the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft centerline.

Some might refer to the camshaft as the brain or heart of the engine. It determines when, how long, and how far the valves open and close in relation to the pistons. For every two revolutions of the crankshaft the camshaft rotates one revolution. On most overhead valve engines there are two main types of camshafts, either a flat tappet camshaft ...

Net valve lift is a function of camshaft lobe lift and rocker arm ratio. Lobe lift (sometimes called cam rise) is the height of the eccentric portion of the cam lobe above the base circle. The rocker arm transfers the motion of the valve lifter riding on the cam lobe to the valve and increases the lobe lift by the amount of the rocker ratio, which is typically 1.5 to 1.7:1.
