318 vacuum advance

distributor is for a 1978 ram charger with a 318

Which one? The one in the car or the one removed?

timing was set at 0 per manual for the motor.

What rpm did you set the initial at?

I assume you mean the '69 Dodge Shop manual spec for 318 with Clean Air System.
The distributor you have, if it really is to specs for a '78 truck, is probably set more like a non-CAS.
Parts store distributors are sortof one size fits most so lets not count on that being 100% like the oriignal '78 ramcharger.
