Ignition question
Locked out? You mean there is no advance in the distributor at all? Set it where you think it makes power, IE 32--36 and see if it moves with change in RPM
If your balancer is not degreed, you'll either have to mark it, or else get a "dial up" timing light
I would start with the very basics..............Use a piston stop to check timing marks are right, measure around the balancer if not marked, and mark it out to at least 40 degrees
