What have I got myself in to? Denver here we come!!

Very nice project. Others will follow your lead.
I'm presuming your PS is working fine?
Also, what electric fan setup did you use?
I'm planning a 5.9 carbed setup into a 69 Dart. Maybe I'll even do the AC and IP since you made it look so easy. Have you finished trimming out the dash? I'd love to see pics of the end product.
