Thanks for the welcome. I did not see an "introduce yourself" section of the forum so I posted here.
Re: LS3 : we've done bigger LS transplants in the past so this should not be too difficult.
Not sure what I'll do with the LS3 just yet. It was supposed to go in my 2001 Vette but that has been back-burnered so the Tahoe gets it instead. All I can say now is it will have one of our radical cams, run a 2008 Vette PCM & wiring harness and be 100% drive by wire. Beyond that, we'll see.

Oh yes, installed a new reman steering box, pitman arm and idler arm today.
I had the dreaded and absolutely horrid OBS steering; it drove like a 1920's silent movie rear projection driving scene - you know the ones, where the actor is yanking the steering wheel from side to side in huge sweeps. That's how my Tahoe was. It was terrible.
Previously changed the electronic variable steering sensor and added new tires which helped but didn't fix the slop. The changes today fixed all the slop. Drives like a new truck.
Next up are the upper A arms, lower ball joints and all the tie rods and idlers this weekend.
