***update
tore the 5.3 down to a short block last night, looks pretty good inside, except for the sludge...... gonna pull the mains out and check out the bearings, see if the y are worn or anything from the coolant that went through it, motor ran good, had great oil pressure even when warm, just needed some new heads, we've done several at the shop over the last couple years, and they all are still goin from just slappin new heads on em, and they were sludged up worde than this one was, if everything looks good on the rotating assembly, may have the crank measured, if still good, may have the block vatted and the crank micropolished and slap some new bearings in, Lookin at some cams right now, but it's a ful roller set up on these 5.3's so it's gonna be a bit pricey, a friend gave me a S-10 grille, which i think looks better than the GMC grille it has in it, other than that, the truck is still at my friends house, he may be startin to pull the old motor tommorrow if not all muddy/snowy around it.
