Well, from what i have been learning, a thumping idle, and a car with good street manners for weekend cruising may not go hand in hand. The top priority is driveability and reliability, so I guess the idle not so important actually. Hey, I'm learning still. First Mopar. First restore and engine build. As far as off the shelf cams, It seems like the Crower 271 or the Lunati 702 or 703 are popular.
