OK, so if I use a 2,5 it really doesnt matter what year i use seeing as how different pistons are going to be used anyway correct? What about the crank and rods? Are they different from a standard 2.5 as oppased to an SVT? i can save some money on a used motor if they are the same. The Extrude Honed heads and intake i dont care about, porting is definite along with custom cams. But if the non SVT motors dont have a forged crank its completely out of the question.
