He says do it at full throttle.

He can. I'd like my parts seated a little before I hit WOT

Actually alternating between full and partial and a little deceleration. Makes sense to me. On a rebuild where you are sure of your tolerances. On cast or moly rings I think...dont think chrome would breakin that quick so maybe no bennefit...dont know.

This is not anything new, Big Daddy Don Garlets master machinest was a buddy of mine father, he taught us kids motor building. This is what we use to do back in the early 70's all the time with 66 and 67 GTO rag tops when ever we would rebuild the engine (drag racing mid 11's street legal too) get it in the car, start it up, get warm and valves rotating. Then take out for burn outs and a couple of WOT runs throught the neighborhood, then off to the track, dove it too. I have always broke in every new car of mine, HARD and FAST. Never had a problem!

Drive it like you stole it!!

That's an old racers trick from the 60's. I was told that the 340's break-in was to run it to 4000 rpm for about 15 minutes after it gets oil pressure as the break-in. I always broke-in an engine how I was going to drive it.

Lmfao you got it warm, i start them set timing and instant funny car burnout, then turn around another funny car burnout, check valves and then hook it on a full pass

so you guys agree this process would work on our older bigblocks?

haynes manual recommends a similar break in process.

The Detroit Deisel generators I worked with in the Navy were always broke in with 100% load (1000 kW) for 1 hour and then considered broken in.
