3.73's around town w/ 33's

[linksvu]

I am probably going to simply keep my 33's, even after the 4" suspension upgrade; what do you guys thing about keeping the stock 3.73's for mostly around town. I am trying to get the best mpg (which is why I got the 6.2) but so far the best has been 17....do you think 4.10's would help for around town?

Maybe I could get my turbo to kick in a bit sooner anyhow...

I wish I had the torque curve of a diesel . I am driving around with 33 and 3.73's ....... with a 305 still

I wheel mine too . Drive with it in overdrive almost all the time too . And contrary to popular belief , it works well enough for me to forget regearing my 83 for a long while

Well, the plan is to make bio-diesel here soon, but that is a whole different post... right now, at $3 a gallon, I would like to get the best mpg; even if that means changing my gears.

How do you like the 305? I almost bought an '84 w/ 305 for the 4spd it had, wish I did.

With that combo, you'll be just fine. I ran 33's, 3.73's, TH350, 350 combo for a long time and easily pulled 15+ mpg on the freeway in my '74 blazer. You should get a few mor mpg w/ the 6.2.

People drive 3.73's with 35's. If you have the power, you probably have the best gears you can get

I'm running 3.73's with 35's and a 350/TH350 and it's great... not the best acceleration in the world, but more than enough for the bone-stock 350 to get the job done... freeway or off-road.

I liked it enough to leave it alone for 5 years Its got 165 thousand on it now , its coming out for a well taken care of 350 until "someday" comes and I go with my namesake 383 .

I wish I had some more torque for long grades in 2wd , and a little mre stoplight ooomph . However its good enough to wheel with , and if I need to pass a car doing 35 in a 45 , I can blow around em

I had 31s with 3.42, that was sporty enough for town and climbing. I've changed to 34s for more clearance (ya right pal), so I'm going to 3.90.

i am also running 35's with my 3.73s, but i have a 700r4. its not a speed demon, but i have my 1976 vette if i feel like going fast
i drive it around town and 41 miles to and from work on the highway at
70mph no problem

I'm running a 350ci (4brl), SN465, NP205, 10 bolt/12 bolt with 3.73 and 33x12.50x15 tires..and it does fine so far...no idea what MPG I get, almost afraid to check it, the wife might try to make me sell it!

just curious, what diff you got that takes a 3.90:1?

laughing at me for the play on words, its a no-diff diff. Corp. 10b, 8.5 ring gear. Its not factory, its more of a street/strip ratio, in this case made by US Gear/Strange Engr. Yes there is a culture of "its either 3.73 or 4.10". I'm getting them from West Coast Differentials.

 

[DEMON44]

my dodge is pushing 35" m/t's with 3.55's just fine........well the cummins & nv4500 help

 

[linksvu]

The NV4500 is a dream! Here I go again...

 

[killerK567]
