Default Question about cam noise

Which cam would make more noise....

shorter duration with higher lift
or
longer duration with shorter lift

Just curious, my buddy's C2 sure make a lot of valvetrain noise. He is gonna get soem Yella Terra to see if he can quiet it down some. TIA

Lower lift will make less noise. However, low lift and steep ramps will also make noise.

Short duration and higher lift will probably make more noise, as the lobe is having to lift higher in a shorter amount of time...and that probably corelates to a steeper ramp.

Yep, that's right if you're talking about valvetrain noise. Some people that have the Comp 218/.563 cam say it sounds like a sewing machine. That's a pretty mild cam but it has steep ramps. The trade-off is idle quality; the low-lift long-duration cam will lope like a ***** . . . C2 has a great idle for a 224 cam.
