what rpm can it take?

[ols0051]

Now that the break in period has been brought up, How long should a new motor be broke in? Everyone has their own version. I have run my new motor for 15 minutes on the first start up and total time is about 40 minutes. Most being on jack stands with the wheels turning. (new tranny too). Also changed oil once and opened a couple of oil filters to check for debris. Found nothing abnormal. I am wondering if I make a few laps down the track at slow speed (to make sure the wheels are going to stay on) if everthing checks out can I hammer on it? or should I get some good run time first?
