shiiittt the reason i bought my truck from where i did was due to the fact the service manager is an awesome lady and said " do what ever work you want to do to it and ill fix it... just be aware that if a ford regional inspector comes in to look at it for warranty work they might say no if you bring some kinda race truck in"
my trucks just a 450 that well pulls my equipment, my drag car, or pulls up to something at a stop light that needs to be showed this big ol truck aint slow. i
