Near me is a N/A 3800 for sale from the junkyard. At least it was a year ago when I was looking for a 3800 to put in my SE. But they wanted $550+ my core after I swapped. Also, could I top swap a N/A 3800 and just drop it in and go? Or does it have to be tuned for that? I don't have the stuff to tune my car unfortunately
