It makes sense to shell out the $6,000 to get a stock 400+ horses that can easily be pushed up to 600+ but who is going to do it first?
So who will be first to drop a new 5.0 in their S197?
Your such a geek!!! lolUm, Ford Motor Company already did. You see, the 2011 Mustang is still an S197, albeit a much improved version over our 2005-9 models.
Much expense and effort would be needed. Let not forget the little stuff like the power steering programming n more I haven't thought of.
