What do engine builders do when they build one and immediately put it on the dyno. Some say once it reaches operating temp. its broken in. They break in the cam and bring it up to operating temps, check everything, and then full pull. My dad and I took a fresh motor to a dyno once, guy had it in his garage. Warmed it up and broke in the cam. Checked eveything and then a full pull.
If its going to break you would rather it be on the dyno. My rebuild I went from installing it at the house, running it some at home and then took it to the dyno. Ran it on the chassis dyno at varying RPM, checked oil, leaks, etc. Then made about 20 pulls. Been perfect ever since.
I say put it in and get it warm to a few times and vary the RPM's, then take it to the dyno and see what happens. Lot cheaper/easier to have a problem on a dyno close to your house rather than at the track.
I also agree with the oil changes and a magnetic plug to find out if you have any issues from the break in.
May also want to you regular oil instead of synthetic.
