Whats better timing?

If you have a M/T or a low stall TC, all in by 2000 IMO is too fast. The M/T car for sure will be a little jumpy, and tends to be like an off/on switch when gently rolling on the throttle, in the lower sub-2000 rpms. All in by 3000, works better for me. But best will be if you had a vacuum advance.

Engine will make more torque and power running hotter. Just so long as it doesnt have an overheat tendency, which on your combo should be easily solve-able. I have run mine at 200ish for 15 years. Easier to tune too.

Like I said before, sneak up on the max timing. You will not notice the difference going 2 to 4 degrees less than optimum; but the engine will notice 2 too many.Better 4* short that 2* too many. But then I run 87E10 on my combo with zero problems.
