The top 5 guys in my class all run sb2 setups that regular rev to 10k and sit most of the race between 6500-8500. One of the guys showed me his data logger where he hit 10700 at one part of the track almost everytime and that was a 25 lap race.
I know what it takes to get rpm out of an engine I am just looking to see if a small block mopar can do it reliably
