What's going on guys, I tore down my 5.3 to replace the bearings and rings what's a good set of bearings and rings? I was thinking Hastings or Total seal and some Clevite bearings, if I have to have the block bored what is an OK tolerance? If it needs bored I was going to have them take it to a 3.898 and find a set of flat top pistons, I'm not 100% sure if I want to turbo this motor or not but what I am doing is a LJMS stage 3 truck cam, PAC springs, TH400 trans, factory 10 bolt with 3:73.. going in a 1985 C/10
