Ahh okay. Well that's not going to happen any time soon then unless for whatever reason I need to drop the pan for something. And if that's the case then there's probably more problems than that lol. How many different factories were the 5.4s made in? I know the trucks were made I. A bunch of different factories cause my truck came out of the Norfolk VA factory but how many for the motors?

Since we are talking pi swaps. If I were to take a 98 lower that is in good shape and swap out my heads and intake. 1) would I need to have a custom tune 2) what grade gas would be my minimum 3) what numbers could be realistically expected?
