thanks that's a good starting point for me.. my location doesn't have 93 octane at the pump so ill compromise and come up with something close.

My 1340 is about 14:1 and have it tuned for 87 octane non-ethanol and have run MR12 straight up with no problems.
Do have a pretty big set of cams with wide lobe centers.
Use caution your results may vary.
