Need a smooth idling cam
I want a cam similar to a stock 02+up Z06 but better. Does anyone know of a good aftermarket cam with a stock idle? Sound clips would be appreciated if you have them.

Some people like the 220 cams and I've heard the 224R can be pretty tame... but I am waitin for a 232/234 cam to come in.
Everyone says "Its all in the tune"; if you get someone to tune the car after the swap, it will run and idle great! Don't skimp out on the tune ($4-500 ish, right guys?) Also, I believe the Lobe Separation Angle (LSA) needs to be higher for a *better* idle, depending on what your definition of better is. 114 LSA or higher for your needs, lower for a choppy grumble.

I will do the tuning, I have a wideband and HP tuner as it says in my sig. I want a cam that has a idle EXACTLY like stock, they did it with the z06 so I would imagine someone in the aftermarket makes one. Maybe I should just get a custom grind?

^ Just what I was thinking... Just enough lift and duration to feel it...

Thunder Racing Custom Camshaft
"CheaTR" - 214/230 .601/.575 117 LSA.
Off Idle-6800 RPM Power Band. Broad power range. Works well with stock exhaust manifolds and catalytic converters. Stock like idle. Minor tuning required on automatic transmission cars. Responds very well to nitrous. Due to the fast ramp rate of this camshaft, the use of 1.8 rockers is not recommended. Double valve springs and titanium retainers required for this cam.

The other stealthy grinds do have a slightly irratic sound to them.

I've heard good things about the GT2-3. I have heard that it does have a slight loop at idle and I've also heard that it doesn't so I'm not sure about it. Then again I've also heard exhaust clips with the zo6 cam some have loop others don't, I guess it IS all in the tune.
