av gas?

Not an issue for race cars, but if you have a street driven musclecar I found a problem.

With high c.r. like LS6 and L78 and even a Stage 1, it would always blow a baffle loose in a stock muffler. At the time we had a small municipal airport and no one cared if I pulled up to the pump for LL100.

Later I read info that the problem was caused by the LL100 being too "hot" or too "dry" and therefore caused the problem, but not enough detail was given for me to understand what that meant.
