Hello, I am thinking of buying a 70-71 challenger as a project car. I am torn between getting a 70-71 and putting a 440 with 4 speed or buying a new 392 challenger. Where is the best place to find cars? I’ve looked on racing junk, but all it looks like it is all gateway classic cars for sale. I was hoping to spend around 40k when all said and done with the project. Thank you.
