Won’t start, again

Good morning, figured I’d post up since I’m sitting on the couch drinking coffee this morning.

1969 Dart 360la, 727. Ran and started fine prior to me messing with it. I replaced plug wires, and a ground from the floor shifter, car was down for about a month and I didn’t put the battery on a tender.

After charging the battery the car tries to crank and sounds fairly strong, I can see fuel squirting into the carb. I took off a few of the plug wires one at a time with the plug, held to the block and got spark. Have all the plug wires in correct firing order.

All I can think is pulling my truck battery this weekend and trying that since I know it’s good. But like I said the Dart seems to crank OK with the battery that’s in it.
