Timing Curve on 360 in an RV

What rear gear and tire roll-out? this will play an important roll in avoiding detonation on a long pull.

I can't figure out why you would chose all-in at 2200; and no vacuum advance. That is a race-car tune, with a lightweight car, a big engine, and race gears.

With the backfiring issues I was having, I started to bring total timing down and could only get rid of it by getting down to 20 degrees total with no vacuum advance. I went all in much earlier after seeing some charts where the 360s were all outta torque by 2200rpms.

When I was dealing with the backfiring, I was at 16 initial, 30 total with 5 degrees of vacuum advance, all in at 3000 rpms. With these settings, I’d get consistent backfires at 27 degrees of advance or higher (even while in park) and lots of stumbling/backfires on acceleration.
