After a lot of deliberation and thought, I've decided to keep my Challenger numbers-matching original. The car was still equipped with the original 225 slant six and transmission. I ran the fender tag and vin and found that it was an original "light gunmetal metallic" with medium blue interior. I know a lot of people (if not all) have v8 powered Challengers, so keeping it with the six seems odd enough to be pretty neat.
That being said, where do I find some sort of guide to an original restoration for this type of project? I want to keep this car as original as possible and keep that nostalgic feel to it.
