Timing/sluggish/intake backfire

[Red_Dirt_BOY]

I have my resting idle speed at 800/850ish  and am at 10 degrees at 3000 feet on the bell housing view window, however, I am still getting sluggish results and hesitation and at times I hear backfire coming from the intake when going from 1s to 2nd, 2nd to 3rd and when in 3rd if I increase the accelerator too much it bogs out unless I downshift. the air filter is brand-new  and have capped all unused vacuum lines "I think"

Is the firing order correct?

Is the firing order correct?

Yes I have it correct i learned that my new timing light had a degree advance that I was supposed to adjust it to correspond to the degrees on the flywheel or pulley.
it running a bit better but haven't had any backfires but still is sluggish and bogs down but not as bad.
