Not Ranked
Mark,
It was ran for about 30 minutes at about 2000 rpm. It's a roller cam, so no breakin was needed....just cranked it, started it, set the timing, and let her go.
After the first 30 minutes, we shut it down and ran the valves, did maintenance, etc.
Then we did several more 20-30 minute runs (basically heat cycles) with a little load on the engine.
Next came a pull to 6000...and again we checked the valve lash, etc.
Then we made about 10-11 more pulls at around 6500-6600 while playing with timing, jets, vac springs, dizzy bushings, etc.
It was done by Performance Engineering in Cincinnati, OH.
Great bunch of guys.....really hard workers and very knowledgeable.
