So i did some searching and haven't found anything quite what i was looking for answer wise, i hope someone hear will have what i need. I am looking to get a better take off and want to put in a new ring and pinion. I'm thinking a 3.83 should be good, i think i have a 3.07 or whatever came stock with the 82 berlinetta 4bbl carbed v8. Im not so great with cars yet so bear with me haha. I have a rebuilt 3 speed auto th200c with heavy duty shift kit, and want something to give me at least a good chirp at a light without destroying my already terrible mpg (around 12-14 on a good day) i don't cruise a lot on the highway, but when i do its for a long haul. any suggestions on what i should look for ratio wise and does anyone know how much they will hurt mpg and top speed?

me personaly i have 5.0 4brl carb and a 700r with 3.42 gearing and i wouldnt go too much lower. At a certain point too low isnt good beause it kills your topspeed and even doing freeway speed the caer has to rev higher.

alright, well looks like i have a 3.23. Idk how low to go though haha thats where im stuck, i want some chirping at a light but i dont want to be paying much more for gas because of it. If i remember right, the 700r4 is an overdrive trany which is much better for those mpg on highway, and im not lucky or rich enough to have an overdrive so i fear the highway will put a hole in my tank if you know what i mean

 

As the #s get higher, your highway RPMs will increase, hurting your MPG.

So you would want a lower #, like 3.23/2.73 for better highway MPG, but the lower #s will also hurt your take-off, even if just from a stop at a red light.

A 700R4 would allow you to retain take-off & improve MPG. Getting new gears put in & set up correctly can be pricey. I'd look into the cost of a 700R4 & compare that to the cost of gears + having them put in & set up.

 

yeah i still have to give my transmission guy a call to see what he'd charge, but i usually get some cheap deals with him. id love to put in a new trany all together probably a 700r4 or 2004r, but i just had mine rebuilt about 3 months ago and it would be a waste of some hard earned money to throw that baby out so soon. I don't mind a little mpg difference on the highway, i just don't want to be at a half tank after 40 miles. and top speed isn't too huge since i rarely go over 100.

I just want to not only leave the ever so annoying ricers in my dust but leave them there with a squeal in their ears. I'm not saying make them spend hours removing rubber from their front end(but that would be fine with me =P) but something to get them to notice
