10 sec. 318?

So I'm looking at a project car that I would like to turn into a street legal drag car, and I was initially leaning toward a new hemi swap so I could make some good power with low weight, but the more I look the more I think I may be getting in over my pocketbook... The car I'm looking at now already has a 318 in it, and I know you can pretty much make anything go fast with enough time and money, so I was wondering what would it take to get a 67 Dart into the 10's with a 318 and a 4 speed? The hemi swap is looking to be around $6000+ if I'm lucky, but if I can take the 318 and make it do the same thing for less I would consider that as being a good second option.
