Heard somewhere that roller rockers chatter (you can hear the rockers on most new chevy cars- kind of a sewing machine sound). Thought I saw something about roller rockers setting off the knock sensor and creating problems when installed on a TBI motor. Have been poking around off and on for a few weeks trying to dig up info but have not found anything.

???

I've heard issues regarding the knock sensor when using gear drives not anything yet with roller rockers. Why would they "chatter" more than non roller rockers?

I'm runnin roller rockers in my 454 and they don't make any noise at all.
