He was running 110 , Vp stated we were on the ragged edge on compression /fuel, said we should go to C12 which lined up with what the dyno operator had stated.
Car didn't like anything more than 34 degrees of timing - at all.
We tried it and picked up power and, it would take a little more timing, which also helped.
Well, if a little fuel change is good,,, so, we tried some 16 - car did Not like it .
This engine has pistons about 14 up out of the hole.
Our best runs are on the C12, 35-36 degrees of timing in the heat , 34 when its cooler /dryer.
