Continuing ignition timing debate from the 416 thread.

This is a spec. 350 2bbl motor. Fast distributor and fast box. Timing loses less than 2 degrees through the rpm range. Timing set at 5000 rpm. locked. This shows what I typically see. Notice the difference in timing requirements isn't at the peaks but rather above and below the peaks. 30 degrees of locked timing hit the sweet spot on both ends. Not saying in some cases a curve can't help. Just not in every case and the amount it helps varies. Here is a picture of the data with graphs to follow.
Edit: added graph.

This show exactly what I’m saying. It might be the best numbers you are getting but there is no way on this earth it wants 30 at peak torque and 30 at peak power.

You have compromised the tune up to make it half assed happy everywhere.

I’d be willing to bet (not sure what heads they are) that with a 2V carb it would want way more timing at peak rpm but if you give it more it will kill torque like a mother all around peak.
