I don't think that advancing such mild cams makes any difference. They don't have any top-end to shift downward.
Ever try going up on initial in increments? You'd feel a difference. The motor feels sharper, less sleepy. More fun to drive.
Make it your next 'fiddle' project-like the wheels. You can always go back to your numbers if it scares you...  |
I have tried going up and down a bit with total timing, and 35 seems like the sweet spot. That's what I set it to at 3000 RPM. With the 25 degree cam in the MSD that just sets me at 10 at idle; I don't actually set the timing at idle. I use the tried and true silver and blue springs, which brings it all in reasonably early. I could switch in the 20 cam, reset it at 3000 RPM to 35, which would translate down to 15 at idle. That's a fiddle project. But if I'm "getting on it," you know, in between fine restaurants, I'm invariably over 3000 RPM anyway, so all the timing is there.
