How to prepare for engine dyno?

I took race gas and pump 93, extra plugs and my Holley carb parts, jets, bleeds, IFR, tranfer slot restrictors, gaskets and a super sucker spacer. I took the engine unpainted, after the dyno session it was cleaned up and painted.
We primed mine, started it and set the timing and warmed it up and ran the valves then started making pulls. I have to admit I had a lump in my throat on the first pull, he pulled it to 7200.


Super sucker

Every time I've seen one back to back on a dyno session they make more tq and more hp. 10-20 more everytime.
