[QUOTE="macvette, post: 94868, member: 262"] I had a 1963 Corvette 11.25 to 1 comp ratio. It had a factory original blueprinted motor red lined at 6500 rpm, standard engines were red lined at 4000 something.The timing marks were on a harmonic balancer on the crank pulley. If one had an original balancer which was rubber mounted to the pulley flange, the recommedation to set the timing was to diconnect and plug the vacuum advance at the distributor, set the motor to 1500 rpm and turn the distributor so that the motor ran fastest then ease it back a touch and lock it there. This was done after setting the points with a dwell angle meter. Reconnect the vacuum advance and reset idle. This was recommended because of the elimination of lead tetra ethyl anti knock from fuel and to take care of any creep in the rubber mounting of the balancer. I guess this was done so that the distributor mechanical advance was operating hence the timing was right on the advance curve. Mac [/QUOTE]
