I have a 2.76 8.2" 64' Lark . What are the largest (numerically) gears can I put on that carrier ? Thanks , Steve
3.08 or 3.23's if you can find them .yet if you feel safe with a spacer plate , you can use up to 4.56
Thanks , That opens up some possibilities . I thought maybe 2.93's at the most . If I ever get close to the road I would like to stick 3.23's with 455 / 400 that's just itchin' for a new cradle ! The engine will be mainly stock for now since it runs great . I'm sure it'll push the 64' nicely . Eventually I'd like a 200 4r / 3.55 -3.73's with a Posi . I'm a long long way from that worry though . Steve
Pontiac 8.2 carrier aka as the '64-67 8.2 BOP 10 bolt rear had the following ratio splits: High ratio: 2.56 & 2.78 mid ratio: 2.93, 3.08, 3.23 low ratio: 3.36, 3.55, 3.73 (very rare), 3.90, 4.10, 4.33... 5.57 Got Posi? :3gears: Roger
To use any of the mid ratio gears on the high ratio carrier, will need to use a propperly installed MrGasket 8.2 Chevy ring gear spacer & red loctite. Got Posi? :3gears: Roger
No, not on the HIGH ratio Pontiac 8.2 carrier, not without having to grind the end of the splines on one axle to shorten it. Then, have to worry about the other axle thats not fully splined up inside the side gear. Got Posi? :3gears: Roger
Just for the record, the 2.76 gear is TALL and a 2.29 would be even TALLER. You are looking for "shorter" gears (i.e. numerically higher). -BC
