Davin-

I live in Sacramento and can help you out if you would like. Like fast66 stated, walking you through the whole process on a message board could be a drawn out process. Maybe we can meet up somewhere and run through the basics. Send me a PM if you are interested.

ORIGINAL: fast66

I highly doubt you dont have a harmonic balancer. WITH THE ENGINE OFF. Get down underneath you car, and have a look at the pulley. the lowest one. that is bolted with either three of four bolts to a round disk. that round disc is your harmonic balancer. these often get very diry with oil and dirt, so get a rag soaked in kero, or petrol, and clean in up as well as you can. there should be a few lines marked on it. one of these will either have TDC or '0' on it. This indicated the Top Dead Centre Position when lines up to the pointer.
Now on a samll block, there is a finger coming from the timing cover, which 'points' to these harmonic balancer marks, its called the pointer. Im not exactly sure where this is on a 390. someone else on here will help you with that if you cant find it. when you do, clean it too.
Now to use the timing light. Put up a link to the actual type you bough. We need to know if it uses an inductor or if its diredt plug in.
While you at it take some shots of your engine and put those up too.
this is going to be a drawn out process over the net.
sorry i was being stupid i have one but it has no marking on it at all. i tryed to clean it its smooth as can be

Why do you think your timing is off? Mine has been off on 2 cars so I know the symptoms. Bought a timing light for $50 and it was a good investment.
