Unhappy The dyno says......

Not quite what I had hoped for, but some room for improvement. Ed, the dyno operator suggested:
1 - ditch the Stelling & Helllings and over oiled K&N - 20 HP difference in the runs with and without the air cleaner
2 - Too much advance timing - get it to 36 deg max
3 - Take the carb jets down 1 or 2 steps
4 - Change the accelerator pump cam for a bigger shot

Next step would be a cam shaft with more lift. Got an Isky with .525 right now.
