I realize you're teasing, but I read the same thing. Seems that STOCK motors had lower compression starting with the 2.4 and should run better on lower octane. My '71 S motor has 9.8:1, I believe. So, I need the good stuff or better (read blend of small amounts of race gas). So, in terms of today's gas and ratings, what is the best gas for the 8.5:1 2.4?
