No spark

[1986c10]

Hey guys, havent been on the forum in a very long time. Just picked up another c10, its a 1979 and is a 95% done project but they werent very wire savvy. The engine is fresh but has never been fired and the guy knew no details about it. It appears to be a .030" over 327 with some bolt ons. I got it to crank but it wont fire up, it acted like it wanted to but I didnt want to crank a fresh engine too much. I adjusted the float height (it was spraying fuel) and fixed 3 seperate fuel leaks. Then I decided to verify distributor timing, found that the distributor was 180 out, I restabbed it, now i have no spark. I have 12v to the "batt" wire at the distributor. I took apart the distributor and found that the seconday resistance was ol, bought a new coil and resistance is now in spec. Still no spark! I'm going to add an additional ground from the engine to the frame because the current grounds suck. Any other thoughts on how I could not have spark? Or what I could have messed up as it did almost fire before so it must have had spark. Thanks in advance!
