I might be wrong but Im pretty sure the alum. 5.3s have iron sleeves. so boring might be possible if this is the case..

It definitely has iron sleeves, almost all aluminum engines do. The point was that you can't do a real heavy overbore on these 5.3's because there isn't enough sleeve material to maintain wall thickness. Not as bad as an LS1 (which can basically only tolerate a hone), but just not worth the hassle imoOriginally Posted by kyle.p12
