what gear?????
 
I have my 3.23 gears that i would have to pay like $350 to have it put in. Or should i get a whole rear end with 3.73's? I am already bidding on the rear end here it is if u wanna see it. http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEBI%3AIT Keep in mind this is waaaaaay cheaper. Is 3.73 too high for my car?

Depends on what trans and what type of driving you do and/or plan on doing...give a little more info and we can give you a little more help

thank you for not throwing out a ratio (I know you know what your talking about anyway) what mods are you planning for the engine? any gear change will change the rpm range of the engine all things to keep in mind

Well its not gonna be a daily driver, i don't care about gas mileage since its so bad anyway. I don't care about goin really fast top speed either. I have a /th-700R4 i believe if thats what a 3 speed w/ O/D is. I plan to take it to the track every once in a while. I also am planning on dropping a 350 in it

How about some 513's.:D

blue89vert 03-11-2006 10:52 AM

ya so my top speed would be about 50. lol

Given your tran and your driving habits...

Autos typically like a 3.23 or 3.42 ratio for the street. A 3.42 will obviously give you a little holeshot, but will hurt your top-end and highway RPM a little more.

Personally I think the 3.73's would be a little high. They would help you get going with the 305, but once you put in a built 350 you will run out of gear.

I would almost recommend the 3.23's, 3.42's at most. You will be happy on the street, and you can also go on highway without having to cruise at above 3 grand.

thanks

im not too worried about the highway, but would 3.73s be ok for the street? Would they be ok if i kept the 305? How much top speed would i probably have? I appreciate all of your help.

do you mean its a 3 speed plus overdrive or its a 3 speed with overdrive. theres a big difference. if there are 3 total foward gears its probably a 350. if its got 3 plus overdrive its the 700.

archemedes 03-13-2006 03:34 PM

the 305 works better with the 3.23's from my experience

That kinda confused me but its got 4 gears all together

blue89vert 03-13-2006 06:22 PM

would the 3.73's be ok with that trans? I know its kinda high but its the cheapest way to fix my car....right now i am unemployed but go back to work sometime in april. I would probly put the 3.23s in when i get the extra money or i would just upgrade to a whole new rear end. Whadaya think guys? :feedback:

archemedes 03-13-2006 06:27 PM

basically it will work, but teh engine won't be in it's power band much

blue89vert 03-13-2006 06:30 PM

will it perform worse?
