Dude, it can take FOREVER to swap an engine, shoot...I just swapped a fresh, rebuilt KA-T in and its taking me forever to get it running. Electrical gremlins own me

Also, if its at a shop you have to consider other cars that might be in line before you etc. 2 weeks would be REALLY fast to get a swap in and running perfect imo. Have you ever swapped a motor? It's more work than you might think, especially if you freshen up a lot of stuff.
