It is a very bad idea to install a high performance camshaft in a heavy car with an automatic transmission for the purpose of creating an impressive idle. Your customer will wind up with a stone that sounds as though it needs a tune up. You are better off pulling a plug wire.
High performance cams with high lift, duration and overlap are intended to move peak useful power up the RPM band, mostly for competition purposes.
Most fellas I know who sought a cam shaft for an impressive idle were sorely disappointed when the car had less low speed power and more fowled plugs. I strongly advise against using anything but the stock camshaft grind unless one is going racing. That is a different story. But for tooling around on the streets with a letter car, a "performance" cam will be a liability.
