Ok so I have the money to order a tested and working 4bt. I don't plan to have this actually installed and done till this time next year. I know that a guy can go and pay 20 grand for a swap with some bells and whistles, but I want to do this on my own, since I have no real deadline.
So I'm looking for input from anyone that has done this on their own, anyone who runs a 4bt regardless of how you got it, or anyone that has any input on such a home build I should be aware of.
