5.3 Rebuild... need some opinions

[JNJchev77]

I am in the process of teardown and rebuild of my 5.3/LM7. This motor came for an 03 Tahoe with about 120K on it. It's going into my 77 swb c10 and I just want some opinions on how far to go....

Basically what I'm asking is, do I really need to take it to a machine shop? I'm basically doing a stock rebuild, except for LS6 cam and springs (and pushrods) and possibly an LS6 intake down the road. The motor has no unusual wear at all, looks very well maintained, etc. etc... I do plan on using all new ARP bolts for main caps and connecting rods, as well as all new bearing, seals, rings, gaskets, oil pump, lifters. This is my first LS rebuild, I've done SBC rebuilds without machining and haven't had any problems... but these motors are new to me.

What are your opinions on this?
