Been searching on here and Google for a while and can't really find what i'm looking for. My engine is at the machine shop now and I want to break it in properly when I get it back. Since the truck is not complete I'll have to break it in on a test stand or sitting on the bare frame. I know to drive it 500 miles easily and then change oil and all that stuff but since I can't drive it, how long and what RPM should I run the engine at to break it in "on the bench?" Thanks
