Larry,
Does your fuel warehouse handle any other brands?
The Purple Standard is a pretty good fuel. You might get some more power out of a slightly lower octane. The following spec is what is shown for the purple:
Motor 105 R+m/2 110 Research 117 Octane Diff 12 Spec. G. .725 Reid V.P 8 Dia. -.05
To get a better low compression fuel you would need C-11 It has a lower octane & the Octane difference is only 2 which makes it a little more stable & a higher quality fuel. It's specs are:
Motor 104 R+M/2 106 Research 110 Octane diff. 2 Spe. G .717
Lead 4.23 Reid V.P N/A Dia. -1.1

Fuel is just something you need to test to see what your combo likes, Esp in your low compression engine. Some fuels might look good on paper, but might not like your combustion chamber, spark plug locartion, Piston shape, RPM,ect, ect. There is not a one fuel does all, that I know of... guess that is one reason VP markets over 54 different types/blends.
