323 or 355

Pretty sure you had meant 60 series tires. Between the two, considering OD, definitely the 3.55s.

If you are willing to consider other gears. 3.73 or even 3.91 are great with the 833 OD

lets say I do not have OD
 
You will get opinions all day long, just work out what RPM you want to turn for how you use the car and do the sums. You can use an online calculator. If you don't have an OD trans and you have an 8 3/4 rear you can always swap between centers with a 3.23 and a 3.91 or what ever, not a big job to swap over.
 
The MoPar 4spd-OD trans is a little bit of a pain to work in a good gear ratio for a double duty car. Ether the first gear ratio is to much or the OD gear ratio is to much. Fitting in a cam to work with both gears leaves you on the small side of a cam shaft. Which is not so bad unless your idea of engine performance is way out of the normal street driven hot rod.

3.55 X .69 OD (is this your correct OD ratio?)
equals 2.45. (2.22 for 3.23’s!) That’s the same ratio (2.45) they used in the gas crunch era for maximum mileage. That ratio doesn’t work well even with small performance cams.
With 3.90’s, it’s 2.69!
4.10’s are 2.82!
4.30 = 2.96,
4.56 = 314....

With that 3.00+ first gear, even the 3.55’s seem useless. What the heck is the other ratios going to feel like?
ZIP! And your done! Probably lots of smoke with the most modest pedal application... LMAO!

It’s a tough balance act. The trans works best with low to mid 3 series gear and mild cams.

thanks for the lengthy info, also let say i go without the OD
 
Sorry, I thought you were using the OD. My bad, nevermind.... moving on....

Having fun jerking everyone here? Go to posts #3 and #17 and figure it out yourself.
 
I am serious do not know if I am going with OD or not haven't got the 4 speed a-833 trany yet

I'm serious too. You can simply do as I suggest, post 3 and 17, and go and figure it out yourself for all the different 4 speed vairants out there.

not here to jerk anyone around just new to mechanics this site has helped me very much, so cool off
 
.....new to mechanics....

Sometimes you just have to do the work. Good news, 3 minutes on the internet and 1 minutes with a calculator and you can answer your own question.
 
We drove to Detroit for the Charger 50th in 2016. 275x60 15`s. 3:54 gears,4 speed.
3400 rpm at highway speeds. Would have to look, but I think it was about 1100.00 in Canadian for fuel, round trip, 4200 miles. I might be off a little.

Oh yea! That’s what I feel like happened to me and then given a jerk *** reply. With the below post, now I know we have a lazy *** ******** here.

(so much for trying to help a fella out. No good deed goes unpunished! Again...)

Thank You BSB67!

Actually no, never asked for help on something as simple as a gear ratio, but that's not the issue.

Have you answered post 3 and used the link in 17 yet? What did you find out?

You'll have a hard time getting help from others when you jerk them around, and don't try to help yourself.

Truly, good luck
