Re: Is this a good running gear setup?
3.42 would give you a better off the line ratio than a 4.11 and 3 speed auto, while giving you the benefit of a final drive ratio of 2.4. Go too steep with the rear gears, and the 700's 3.06 1st will be too steep, and much less than 3.08 and you have the wide ratio from 1st to 2nd dropping RPM too much and hurting performance a little. IMO 3.23-3.42 for a SB street combo would be ideal.
69 Malibu. It donated it's ZZ4 to my stepside, so a junkyard 454 is pending. Stay tuned....
