Ok so I went to a car show on Saturday and I,m getting really tired of 3,000 rpm when i,m going 60. So here is what I have! 71 RR with a 440+6 auto trans and 4:11 rear gears with P275-60-15 rear tires. Going to change the rear gears so do i go with 3:55 or 3:23 . I,m afraid that 3:23 won,t give the low gear kick that I like. Opinions Please!!!!!!!
