What are you burning for fuel? Mine has 225 psi cranking, run 22 initial and 36 total timing, and it's got to have the 101 unleaded they sell at the pump out here.....at $7.87 a gallon. That's still cheap by race gas standards, but there's no replacing high compression for that snappy throttle response and that sound!
I only usually burn less than a tank or less a month(30 gallon tank), so the price difference between the good stuff and premium at $4.35 a gallon is not that drastic.
