Rebuilt 318 install problem

JoeSBP said
I would use an actual piston stop, and mark the balancer to ensure you are dead on TDC, and your balancer has not slipped.

HEI, or electronic distributor? What year/vehicle was it ordered against?

I would start with timing it right at 0° TDC, and get it running, then dialing it in..

The balancer is brand new.

It was ordered against a 1974 Dart with the 318. I am running that distributor with a GM module and Dodge truck coil as described on the forum.

I've tried starting at 0 also with negative results.
