Default what gear-ms4 + Spray??

Im looking to pickup a 9" setup and trying to pick out a gear. Im thinking 3:73 3:90 or 4:11. The car is driven around 8k miles a year and will see the track hopefully around 6-8 times a year because its really far away. It has a forged 347 5.3l stg 2.5 heads ms4 cam full boltons and a 200 shot weighing in at 3350lbs. Most of my driving is around town but some highway. Will i run out of gear with a 4:11 what about a 3:90?

Im running an ms4 and 4:11s and make it just through the quarter at the rev limiter. I would go with the 4:11 or I think you may run out if rpm. I have also made a 1300 mile trip with them and still got 23 mpg.

What size tire do you plan on running and how high are gonna spin the motor. You'd probably be ok with 4.11 and a 28" tire with your setup. I run a 3.89 gear in my 9" with a similar setup on 27" Hoosier QTP's and Im trap 130 at about 6500rpms.
