thanks for the info, the cams will be skunk 2 stage 3s and i was thinking with those i could get away with 13.7 on 93

12.5 is the max in my opinion for 93 octane

There is really no telling unless you talk to a builder/tuner in your area that knows how the VTC will affect timing.

I wouldn't try it on 13.7 I did it once and my motor didn't last that long
