Update: I just went back and looked through the 6 timeslips and found a 9.58 @ 75 mph with a 2.33 60'.

HIc--8.9 isn't bad for a RCSB with your mods. I might be watching over your shoulder to see what kind of numbers you can get with the Stage 2.5 heads. I am 100% willing to do some if I can see some good improvements over stock heads...
