Wilf, I can't tell you the details, but everyone including my engine guy said a dyno breakin was the best way...they ran it in on the dyno with a light and varying load (computer controlled I think) for some period of time, watching all the gages and looking for leaks and problems, before running the dyno pulls. I'm like you though, how did he know when the motor was ready for a full power pull? Interesting question...
