5.37 Gear rear end?

[Flash]

Hey found a 489 3rd member with a 5.37 gear and cone style suregrip for sale locally.

How ridiculous would it be to put it in my 72 Charger with a 318? I know it would be horrible for highway driving, but might be fun around town?

In '74 I ran 5.13 in my 340 4 speed Duster that was my daily driver.. Being 17 at the time it was Fun Fun Fun.
Gas was only 32 cents a gallon before the gas crunch. Of course my hourly wage was $1.00
Thanks for the memories !

Didn't A100s have some low gear like that for town deliveries? I remember seeing 13" wheels on some so easier to access bed with ease.

 

[zyzzyx]

Faghetabotit! Change the gear to a 3.55?

Ridiculous. Your 318 will be in pieces before the weekend. Here's a chart. With a 28" tire (common size) your 318 will be screaming at 4200 rpm at 65 mph.

I should say the reason was my Duster came with 3.23 peg leg rear.
So a local racer gave me the 5.13's to use as long as I gave them back. I went with 3.91 after a year or so.

Back in the 60's-70's you could spec ratios up to 5.13 in trucks from Ma Mopar.. We had a 1 ton dump truck with 5.13.
I do agree with the guys you will tire of them quite quickly with the engine revin' 4800 rpm at 40 mph.
A stock 318 is pretty much done at 4500 rpm

How ridiculous ? Not worth the time or effort.

Keep the posi, sell the ring and pinion , and buy a gear set that’s reasonable like 3.23-3.91.

I should at least try the gear out before I sell it right?! Lol

What would be fair for the entire 3rd member?

Be sure to bring along a dust pan!

It would be fun if you are going 1 mile to the store and back.. that's bout it.. i have 4.30s with 30" tires and it's barely tolerable (i will be changing them eventually)

 

[RemCharger]

318s don't blow up that easy. Try em.

 

[padam]

Yes!
Do it just for fun and to say you did it.

I ran 5:13s in my Charger for awhile when I was just racing 1/8 mile.
They’re a blast if you can hook up and you’re not going too far.

 

[Doorkicker]

That's awesome. Pop it in, go do wheelies, and then rip it out and drop in a 323. Sell the 537 ring and pinion.

Yeah that's my plan! Should be a blast and then probably be annoying lol.

What's a fair price based on the condition?

 

[Bird 426]

No. Plus, it looks a lot rust crusty. 5:37 gear ratio? Haven't heard that number before, 5:38? It's still not worth the time and money.

 

[Darter6]

The most I ever saw was 6.17's. Chevy of course
