Hugh, I think I had read that article when you published it. They agreed
that there was no advantage in running premium gas, but I do not recall if
they had actually played with the timing. My guess is that they did
not. But again, given how tough it is to play with the 58's timing, I
don't blame them....

Actually, it only takes a bit of carbon buildup in one of the cylinders to
cause excessive engine knock which could require the premium gas. Bob's
engine may be functioning fine except for the carbon that could build up
compression ratio in one of the cylinders. Also, Bob may be running higher
advance, so his car might be faster than your's Hugh! He is paying for it
though!
