I guess the topic line pretty much sums it up. Will I feel a considerable difference in the torque department with these gears? I have stock 305 TBi basically. I am running a T5. I might go to a bigger engine down the line as well.

Thanks, Eric

yes you should be able to tell a differance

The place you will feel the most difference with gears is when your motor revs up then you shift and it pulls hard instead of bogging. Mine made a HUGE difference.

Oh yeah your car will officially be a gas guzzler. I lost alot of gas milage when I put my gears, so be prepared.

hell yeah you will feel a difference, best mod i have done, gas mileage did change too much, i still get about 23-25MPH on the freeway.

dunerida82

Did or did not? lol :lala:

dunerida82

Also, how will they be on the freeway?

LOL, DIDN'T

Also, if you have overdrive, dont even worry about it on the freeway, RPMs still stay pretty low. I can bring my car up to about 115-120 no problem in OD.

If you can keep off the pedal your milage should be just fine. You will have plenty of off the line fun.

Sorry to minorly highjack the thread, but it is related and why start a new one for a quick question. Any way, i am currently doing the search for gears and posi (posi at the least) but if i were to go to 3.73s in my auto from the stock 2.73s what kind of intown milage (well more like stop and go up to about 55mph) would i see. I am getting about 20-21mpg right now being reasonibly gentle, not slow, but just not wot very often.

firestarter

jokerman,
I have went the 2.73 to 3.73 route before. Gass milage increased due the the fact that you don't have to be on the pedal all the time from stoplight-to-stoplight! but that is in a 1.1 ratio final gear on a th350. w/ and overdrive your cruising w/ a smile on your face. w/ milage on one hand then if you get the bug it'll wake up rather nicely! If memory serves me I went from 11 to almost 15 w/ just that swap in town w/ my foot out of it going the speed limit. but dropped rather heavily if i was playing. Hope that helps. BUt once you do it, you wont turn back!

Jokerman

Cool, ill just save the xtra cash and get the gears and such at the same time ( i know a shop that will do it all for about 250 in labor if i bring em the parts and the labor is waranteed.)

what kinda rpms you turn at 70mph with the th350 and 3.73s?

firestarter

Right around 3k! This is where an overdrive would be usefull. Its all about what kind of performance you want and what price you'll pay for it. You could honestly use the right tranny and gears and get better milage and a better launch than w/ a th350/3.73;s but some people just love cruising down the road up there in the rpm range. But.....I love it because 2800 is right where my car starts waking up! It just worked for me. BUt like everything else its not for everyone. THen again i'm the kinda guy that takes his heater, and speakers, etc... out because it weights too much and the wife is telling me not to rebuild the new engine in the kitchen!

hmmm im thinkin of gettin the 3.73's now, i need new gears anyway i got a th350 tranny and my brother has been tellin me dont go that high ull be cruzing at 65 at like 3k rpms.
its not like i do alot of highway driving anywayand i htink they will help with performace on the track from 3.23 to 3.73s. what do you think firestarter?

sooner or later ill be puttin a new cam and heads on my motor enless that goes then it will be a 383. but for now its stock heads, alittle better then stock cam, and a tight stock th350 converter, that will be swtiched to a 2800 stall converter.

firestarter

sounds like a nice set up. You'll notice a nice improvement from the switch. With a gtech going from 2.73's to 3.72's i noticed almost .5 in my 1/4 times after i learned how to launch w/out too much wheel spin. of course That was also w/ a shift kit. BUt you will notice a definite improvement. going from 3.23-3.73 is a pretty good step for the future. W/ the new cam/converter and heads you will need those 3.73's to make correct use of them. Even w/ all of that aftermarket mods if your intended use is city comute and alittle floggin from time to time you can't really go wrong. Just remember to keep your foot out of it. That will take some getting used to. Install a shift kit and hit second a 6500 and it'll be a good while before you can learn to just take it easy on the throttle. I myself have not entirely learned that as of yet as I have my new engine built up ready for wintertime vacation to install for next spring! I would recomend 3.73's to just about anyone stock or otherwise(unless heavilly modded) just because its a great all around gear. I don't like 4.10's because thats too much on the tires trying to launch. U just can't keep tires w/ them. 3.42's are pretty decent but I would say for mostly light street and a majority of highway use. Of course this is my opinion based on what knowledge I have, or don't at times. Take it as you want it. There are many who will agree strongly w/ me. Yet there are those who will say i'm full of it that 3.73's are too much. I guess what i'm trying to say is do as u want, its your car. I just spend $400 total for my 3.73's and shift kit on my old chevelle and that is by far the best thing I have ever done!

yeah i have a shift kit already in the tranny and it barks into 2nd even with posi. well im fully decided on the 3.73's now just need to get the money and find a company other then richmond becuz of the whine they give you but i might just go with them becuz right now my gears whine alittle since they guy who put my posi in said i need new gears and he got the backlash as good as he could and said there might be a whine but well ill just turn my system up

firestarter

If its whining then it was installed incorrectly and the backlash is off. Thats a timebomb waiting to happen. I would advise to find someone else to install this next set. If they whine you take them back out and set the backlash again and chech the contact patern. Then test drive. And again and again until its as it should be. Always drive it normal for the first 100 miles. Then change the fluid and you should be set to play. Patience first. Ask how I know that one! I went w/ motive gear if memory serves me right. I liked. Got it form border parts in so cal. about 180 i think. I believe you can get some nice ones from jegs for about the same. My favorite place is ebaymotors. Just make sure you ask alot of questions and don't get screwed. But for 400-600 you should be set for all parts and labor. More or less depending on who u know or how cheap you can get GOOD parts! Don't skimp on your rear it'll be a pain later! Good luck. I hope you enjoy! Actually, I know u will!

well the thing is they guy that did the rear end said when he took out the interal parts said the teeth have a sharp edge on them and that ill need to replace them soon. also i think he said it had to do with the pinon bearing, so he didnt charge me to do that bearing or seal. he set the backlash the best he could becuz of the bearing or something being worn like it did. since i wasnt replacing the gears he didnt touch those parts. thats why i got that whine, he does great work. builds tons of race motors from 500+ hp to like 2000+hp and he used to own my car and knows alittle more then i do about it but i trust him more then anyone else around here to do work on my car with out me there.

firestarter

Go to whomever floats your boat! If you say he's a good mech. then he is. And that sounds about right if he was just helping and not messing w/ pulling the gears. Kinda hard to judge people over someones writing. I'm just gonna say go w/ a good mechanic that knows his thing and let you be the one deciding who fits the bill. Sure wasn't trying to come off rude. And if I did i'm terribly sorry. I wish the person I bought my car from was a mechanic i know. Then at least I wouldn't have to go through this why is this here guessing game! best of luck.

I am installing my own rear-gears soon. I am gonna go ahead and buy the tools. I have 2 rear-ends I want to setup and I don't want to spend 400$ for 2 gear installs when I can get the tools for 125$. I think I can do it.

I can't decide on what tranny im gonna run. If I stay 700r4 Im getting 3.73s for the rear. If I get a th350 Im getting 3.42s. I am going to put a mini spool in my 26 spline rear with 4.10s for the track. Actually that rear would probably stay in most of the summer

4.10s will be terrible for the 1/4 mile with my setup but around here its just 1/8th so 4.10s should kick ***.

kfoley

Don't bother with the mini spool, go ahead and get the full size spool. They're much stonger and they only cost a bit more.

88Camaro350

Well for now Im just gonna have the 3.73s with slp posi. I may someday spool the other rear. Buddy is spooling his soon though. I dont think strength will be a concern since neither of us will have that much power.

Hes gonna have a 350 with a mild cam and ported 416's. I'll have a lt4 cam with 1.6s and vortecs. I think a mini spool would be plenty strong but mid as well get the full spool
