and jon...
with 4.10s:
3000rpms at 80
102mph at 5500rpms in third(1:1) gear!
you'll definately run out of gear at the track
with 3.73's:
2750rmps at 80
113mph at 5500rpms in third(1:1) gear
personally i think your happiest gears will be(if you get that 9") 3.90s:
2900rpms at 80
108mph in third(1:1) gear
hope this helps!
