Did the crank spin free after you installed the mains?
Try pulling all the plugs and turn it over. If it spins well than I would suspect maybe #1 was on exhaust stroke instead of comp stroke. If it is not that, possibly cam to crank alignment (timing gears not aligned properly). If it still spins slow, I would check the rings.

I know you have checked it many times, but be sure that your plug wires are in Counter Clockwise order from the top of the cap, not from looking inside of it. Olds distributors turn opposite of Chebby's.

I hope you ground the crank .010 and not .10" !!
So, it spins over OK, but does not fire correctly?
I did see one case where it ran briefly then seized, because engine ASSembler did not wash the grinding crud out of the crank's oil passages. That seized tight though, not an easy spin.
Can you get a local expert to come and go over the setting of spark timing with you? It's 99% certainly the problem, and I don't get the feeling you have a deep understanding of how to set that right.
Oh, and THANKS for your service, I don't think we need to be the world's policeman [unless we get paid for it and I don't mean with $4 a gallon regular...] but I still appreciate the folks who sign up for that service!

randy i have been looking on forums for diffrent firing orders they all say the same but if im looking at the cap should num 1 be in front or back of cap because that might be my issue when i do tdc an point the rotor to num 1 an plug everything up it backfires an no start
