I tried a lot of tuning options. Timing changes, different timing curves, spacers, running at different temps, different lash settings, a little rich, a little lean, it didnt care. It made the same power, within 5hp on every run after we got the tune. That means one thing, MONEY AT THE TRACK. This engine is no finicky and will run strong no matter what the conditions are. The last 12 pulls were almost identical, now matter what I did.
The best tune was no spacer, 86 jets front/rear w/o power valves, 35* total timing, .016" lash
