Mark,
The answer to your question depends on what you want out of the car. It sounds like you are not happy with the original GM equipment. I doesn't sound like you will get your grins cruising around with a three in the tree 6 banger.

The current market value may also help you to decide. If you sell it, will the $$$$s it brings get you closer to your ultimate goal?

I hold originality in very high regard, but in this case since the car is not rare and holds no special historical significance then I personally would put in a Super Car(look) drive train, such as a Motion Phase III L88 M20 and 4.56 12 Bolt.

The fun I would have with the car would far outway any remorse I might encounter for altering its originality.

I would venture to say that if done correctly while still maintaining as much originality as possible that the Nova would be more marketable and that you would be able to get the cost, both parts and labor over and above todays market value as it sits.
