mwebb - if caly98 is only advancing 2 deg, nothings going to be hurt, especially if he drives for mileage, he'll never get anywhere near the peak combustion temps that kill engines. Ideally he'd go through some type of tuner that will only increase spark in a closed loop while cruising at a certain rpm range. But that's much more expensive than just turning the distributor
