    2003 5.3l block, heads

    I have the main caps, lifters. The heads have been completely re-surfaced, but need a valve job, the block has some gouges in a cylinder wall but if you want to bore it out which is what i would do ( to 347ci) it will be perfect. You dont have to bore it out that much though, my engine builder was going to use this block to rebuil my motor so it will be a great block for someone. The block has no cracks, no issues just needs to be bored.Asking price for everything, $450.00 Please make an offer i need some ps loongtubes and some nitrous
