I would be more willing to look for a used engine with low miles on it if possible.. Has the upper intake on you engine failed before??? A lot of the time if the upper intake allows coolant into the oil or crankcase, and its not noticed over time, the coolant getting into the oil will become acidic and start to eat away at the main and rod bearings, and sooner or later a knock will occour... I got lucky, I noticed quickly that I had a problem, and it was fixed quickly... I had even stopped driving the car... It was towed to the dealership.. Its been 30,000-40,000 later and I have had no further problems... I still feel bad for you though... No 3800 should do that to its owner..
