What rear-end gears do you plan on running?

One thing that is awesome about the Chrysler 8-3/4 rear end is how relatively painless it is to change out the rear end gears.

Mine has 3.91 gears in it now, and I'm currently looking for 3.23 gears to swap out. I'm not sure what your overall use is, but mine isn't "running the strip" anymore. I quickly came to remember that the 3.91's are not the best road gear, lol.

3:55. Should be a good driver ratio

Not a lot of progress, I was on vacation in the Philippines for a couple weeks but now back been detailing the engine bay and all the hoses and wires. Tuned her up and she is running fine but can't move because I'm having driveshaft issues as I posted on that forum so any advice is appreciated. here is the engine

Nice work on the conversion, looks really good. I hope you get your drive shaft issue sorted out soon.

Have factory 3:55 sure grip in my A66 Challenger
Was a nice balance between RPM's on highway and having available torque for take off.

Ok folks, new problem. I got my driveshaft issue resolved but now the rear of my car sits 1" lower on the driver side than the passenger side. Is leveling the rear of the car as simple as placing shims/wedges between the perch and leaf springs? or is there a better way? Any help is appreciated.

Are the torsion bars set correctly? this may have some effect on the rear as well.

Update......so I have everything back together and just put on my Mangnaflow X pipe system. Like the sound. Nice low tone at idle then a good snap when you get into it. Drove it for the first time Saturday and the 4 speed is amazing. I Forgot how close the hurst linkage is , not much movement with these short slapsticks. Anyway, check it out and as always, I appreciate your feedback, either liking or disliking, it is all welcome. Here is the Youtube link.

Hello fellow body friends.... well the day before my 59th birthday and I sent my girl off to get taken apart and taken down to bare metal then can't wait for 8 months to pass on the body restoration. Keeping it FC7-Plum Crazy purple but, thinking of a white R/T stripe package? any thoughts. I will post pics once the shop starts to disassemble.

[aussiemark]

The car looks great now, why are you sending it to be refinished?
