So I found out, so far the car doesn't have an engine. The guy who is helping me with the restore, i.e. doing the work, suggests the 426 Hemi in it. I think that's a great choice. If I understand what you're saying, at this point, not having an engine makes doing a "numbers" car not as necessary. I was thinking of doing a bit of a mix between these two cars. I want the body of the orange car but I want the coloring and height of the red. What do you think? (I'll get to engine specifics when I know more. Since I'm getting the car with new seats/upholstery then I might as well decide on the color and overall style of the body now so my interior matches.)
