after i get paid on the 1st im going to be ordering my rear end, im gonna go with a moser 12 bolt. Im running 15x10" draglites with 5.5" backspace and a th-400 transw/ 4400 stall. motor is a 385 with AFR 210 race heads, 10.5:1 CR and 200 shot of nitrous redline is 6500 rpms. This is a street car that will see a lot of track time (weekend cruiser) I was just wondering what gear/tire size combo would best suit my setup, i was thinking 3.90 gears and 26x11.5x15 et streets. What do you guys think?
