I have the 3.0 so like you said it would be a decently easy swap for the 5vz the power the 350 would give me just keeps me going back to it. The 4.3 vortec only has around 200 hp vs the 165ish the 3.4 gives me from what ive researched i could be wrong. For the headache i dont know if that would be worth putting in the 4.3 might as well put the 350 in?
thanks for the reply it helped alot
