For those of you why have high-compression engines in their LBCs, may find this
inteesting.

3 years ago I built a 1500 Midget engine, using all the go-faster goodies,
with a Kent cam and Heppolite 11.5:1 pistons. I knew I was taking a risk, 
because
the quality/octane of gas available is limited. After putting the engine 
together,
and playing around with the timing, I always used Sunoco 94, as anything else 
would
cause the engine to ping very badly under load. Occasionalyy I would put in a 
couple
of gallons of CAM2 (100 octane), advance the timing and have some REAL fun.

Last week I was running short on gas and could not find a Sunoco station, so I 
put in $5 of Amoco 93. Guess what ????? - I runs a lot better than with Sunoco
94, and pings a lot less under load.

Soooo...... does this mean that Amoco 93 has a higher octane rating than Sunoco 
94 ?
I am confused !!!!!!!!

PS - I filled up with Amoco 93 at a different gas station, and the car runs 
just as 
good as it did on the first tank of Amoco.
