What kind of idle can I expect with this camshaft?

This P8 280H camshaft grind is known for producing a choppy idle. This is a characteristic sound often associated with performance camshafts that offer improved engine breathing and power.

What other modifications are recommended when installing this kit?

For best results, it's advised to use headers for improved exhaust flow and consider increasing your engine's compression. A torque converter with a stall speed of 2500 RPM or higher and lower rear-end gears are also recommended to maximize the cam's performance potential.

Does this kit come with everything needed for installation?

The kit includes the camshaft, lifters, assembly lube for proper break-in, and decals. You will need to source other items like gaskets, fluids, and potentially timing components separately.
