Re: running with the key off
Sounds like dieseling which can be too much timing, too rich idle mixture, too hot temp range spark plugs. etc.
Try leaving the car in drive when you shut the engine off. This usually will make it quit but you need to check your timing and tune the carb first.

Agreed with bestracing, sounds like dieseling. I had the same issue when i did my swap and it was timing related.
