What gear ratio?

J Kuchel · 11-03-2008, 09:58 AM

I thought I would change my gear ratio for next year. I need help with picking the right ratio. The car weighs 3200# with driver, BBC, turbo 400 with a brake and Dana 60, a 14-32 tire with a 101 rollout. The engine made 621 HP.@ 6100 RPM and 621 TQ. @ 4500 RPM. Also can someone shed some light on what rpm I should be shifting at? Right now I am shifting at 6400 rpms. The car runs 10.02 @ 132 Mph. with a 4:10 gear. I hope this is enough information thank you for the help.
