Customs 50 Dodge Recommended rearend swap needed

I have a 50 Dodge Wayfarer that has great stock motor/****** with suspension/wiring upgrades. I would like to get a little more freeway speed though. I was thinking about swapping out the stock 3.90 geared rearend for a later model chrysler rearend with something along the 3.0 or 3.23 or 3.55 gear ratio. Whats the pros and cons. I'll will still have the ebrake on the trans, so thats not an issue. What would fit good, width wise..
Would it be a dog in first gear just taking off with 3-3.23 or 3.55 gears.

 

61-65 t-bird 9inch, spring perches drop in place, same bolt circle,
11 inch drums,width almost identical , pick your gear.
Our 51 suburban runs great with a 3:50 gear, 70/75 mph w/o OD!

 

Thanks for your info, I 'll keep my options open. Those early 60's birds are just hard to come by around my area. I was hoping an aspen, volare or dart 7 1/4 or 8 1/4 would work especially since I won't have a tire burner.

 

I am not running a stock Dodge 6 in anything but with a 3.26 gear ( stock Ford gear) and a 28" tire it would be turning about 2500 ( maybe 2600) @ 65 and 3000 @ a little over 70. I think the old Dodge should spin 3K just fine.

 

I have an early b body 8.75 mopar in mine, same width as original .The rear from late 90's explorer works well also.

 

Are you running the flathead 6, if so what highway speed can you run.and what ratio do you run.

 

Jeep Cherokee from early '90s thru '01 (last year of Cherokee) is a Mopar 8.25" . Has the correct width, good brakes, correct wheel bolt pattern and is plentiful.
The most common version is the 6 cyl/automatic and is 3.55 ratio. 6 cyl/manual is 3.07.

However, I think something in the 3.23/3.27 range would be a better choice. Several Mopar cars and Ford 8" were produced in the '60s and '70s that would work well. You need an axle about 59" to 60" wide.

That would make an early Bronco a shoe in then and give you nearly unlimited gear choices.
