Does anyone know exactly what parts are rebuilt in an FQR engine? My 4.6 Romeo is currently in the shop having one of these engines put in and I'm a little stressed out about it. Is just the block reused and everything else new? And do they reuse all your accessories - alternator etc...? What exactly am I getting into here? The parts guy just told me that they had no way to tell whether you were getting a brand new engine or a rebuilt one! HELP!
