For those who have not followed the saga; SOme months ago i took off the top of my engine to change a the gaskets.
I've worked through lots of question on this forum. Special thanks to Rob M. and Bob B who wrote to me offline with lengthy detailed instructions.
My last question involved guessing TDC and timing without visible timing marks.
I was going with trial and error but then my tired battery croaked. I needed a fresh battery for all the extra cranking involved.
Finally, new battery installed, time to try again. lotsa' cranking, lotsa' coughing, lotsa' backfiring- darn, it should not be this hard.
a little googling on carb backfire.
Double check firing order- 1-8-4-3-6-5-7-2
Firing order is correct, BUT IN THE WRONG DIRECTION .
Now for the cool part- i put the wires on right, and it jumps to life instantly !!
THank you

It's gonna take a lot of Adderall to get this thing right.

Funny you should mention this. Some time ago I bought a new high performance distributor from a speed shop for an early Olds engine that came with the advance working back wards the backfire that time cost me a bent rod. Several years later I sent the 455 olds distributor in for a rebuild to a speed shop and it came back advancing in reverse? Sure makes you wonder,not every body has a Chevy.

For distributors of GMC vintage, (not fixed, electronic ones) assuming it's the right distributor in the engine, the direction the rotor turns semi-freely (against the springs in the advance mechanism) is the same direction the distributor turns. Also, if you shot a bullet into the vacuum advance can through the line, the bullet is traveling the direction of distributor rotation. Helps for people with poor memories, like me . . .
