Idle sound

Idle screw.

My 340 has a XE274H. At 600 RPM it has that lazy lopey "muscle car" idle. At 1000 RPM it has that fast racey idle. I keep it at 1000. Better vacuum. Better throttle response. Puts you in the seat and burns the tires every time. I couldn't care less about sound. A car that sounds cool but is slow as hell isn't cool.
