Nice runs.
Wonder how it would run with a 950hp or a 1050 Dominator on it?
I'd try loading the converter more and see how it reacts. Maybe then go the other way and leave closer to idle. Try it both directions. I know when Brian ran his car, the best launch was loaded at about 3200-3500 against the verter, 10" 3500 stall, barely kept from creeping.
You running rancho 9 ways?
