When I was out the other day, over the music of the side pipes, I heard an occasional 'ping'. I am running a 60 over 427 with approx 11 to 1 compression. I am running Sunoco 94 with a lead additive. What do you guys think - use and octane booster or mix with 108? At about 5 gal. 108 per tankful, should get me to about 97 or 98. Also, I don't want to fuss with the timing as the engine is not too friendly at idle as it is.
