I'm fed up with the sloppy opening rate and pull of the stock 454 throttle body linkage. I know certain TBI cadillacs had throttle cams, one I saw was even plastic I believe. Well from what I can tell most any GM throttle body cam would fit right on the throttle shaft but the problem is I don't have a portable grinder in my back pocket to take one off out on the junk yard lot, and I don't want to buy a complete throttle body with one and some yards are finiky about disfiguring parts so I wondered if I can just buy a throttle cam to put on my throttle body?
