Well, I've never done this before but always wanted to. I've done just about every other kind of maintenance/repair in the past 45+ years on so many different kinds of vehicles including my 2002 Tahoe. Always wanted to build an engine. So I just ordered a 6.OL block and will start this journey because I can and before I'm too old to make it happen. This will not be a quick build for two reasons: 1. I'm still working full time+ and 2. I want to do this right, after all it will be going into my 2002 baby.
