123 Distributor

[AudioGuy]

Here's the problem, I have a 1970 280SL has been modified for the Euro throttle body (no vacuum past idle), no emission and the 123 distributor.  I am currently using position 8 but there is not as much power as I would anticipate (rebuilt engine) and according to the information from 123, the distributor only advance 22 degrees at 2400 rpm.  I think the ideal is 30 degrees at 3000 rpm.  What setting do you recommend?

On curve #8, I believe my advance is 22 @ 2400 RPM AND 30 @ 3000 RPM. I believe the distributor no longer advances after 3000RPM but is still advancing at 2400RPM. The engine label says to check the timing at 4000 or 4500 (can't remember which), but there is no significant difference between 3000 and 4000 RPM. Sorry, I can't help with the emissions stuff.
