I'm with bigpoppa on his idea of a "drive-in" cam. An agressive idle is a good thing if you can stand the problems with no low end power, etc. If an engine lopes it does not always mean it's not working properly, it can be the result of cam overlap, carb adjustment, etc. But you have to admit it has WOW factor when idling around the drive-in or where the hot rodders hang out. The more displacement, the smoother an engine will idle. I had a cam in a 265 that was really radical, but when I put it in a 400 it almost sounded stock.
