so i just found out that i blew a piston yesterday. i have a 2002 mustang gt and and i was wondering what would be better for me to do from here just rebuild it with new pistons and seals or go the bigger engine route. i have a buddy that is selling a 5.0 out of a 94 gt. but right now just would like to have some opinions on what to do, just build with what i have or go with a new motor. current mods are bbk 78mm throttle body, bbk cold air, 90 maf, bbk long tubes, bbk xpipe and flow master 40 series. thanks guys much appreciated.
