Thanks for the formula Viking. I slept my way through organic chemistry. I was having a problem with diesling in my new 427. got the timing down as low as 8 BTC and the idle at 700. It still wouldn't stop. I was running 76 "premium" 91 octane and nothing I did helped.
I put in a can of hy-per fuel octane booster
www.hyperlube.com and the problem cleared itself up. They advertise 7 octane points (not legal for street use)... Either way problem solved. I cranked the static timing back to 12 and the idle back up to 850 worked like a charm, but at $8.00 a pint I'm in over my head.
It seems my 10.5:1 calculations were wrong, they had to be closer to 10.9-11 for it to act this way. Either way I will save a ton with 15% Toluene.
