hello folks, well the camaro is finally starting to take off the way I want. new FAT BF Goodrich T/A's in the back, new intake system, new exhaust, rotors, blacked out tails everything. NOW, I'm a little annoyed at the single tire mark at the track, anybody know if its just gears, or the entire axle needs to be swapped for posi? I'm anxious to get some times with my current set up, and i'm hoping the posi will help on my 60' times. also, i'm thinking of re-painting the car i need a poll

Pitch Black or Midnight Blue

 

all u need is a posi unit.

 

Save the money for a paint job
Use a 14" VERY STICKY & WIDE "Racing tire" and you've upgrade the ratio & starting line results.

 

You need a posi carrier, which is several hundred dollars. Then about 200 more for install. Which is why mines not in yet.

Keep the car the stock color. Reason I say this is it will be worth more, and any paintjob on the outside thats not re-done inside the doors, hatch, underhood looks like complete ****. This is again, several hundred more dollars.

 

Yeah I had the same thing. So i bought an Eaton Posi differential. They are expensive and the install is expensive too as was said earlier cuz you will need new bearings which are about $80 i think. The part number is ETN-19599-010 and costs $439.95 at Summit Racing. This differential fits cars with 3.23 and numerically higher gears (almost all V6's). Only some 1982-1983 V6's came with gears numerically lower than 3.23. I bought mine off ebay for cheaper cuz it was used. Haven't had any problems with it yet.

 

A proper set up rear axle is not a cheap cake walk.
Consider other options before committing.
Which is why I threw out a 14" wide sticky tire to be as effective as it could be for the cost involved. Lower rear axle ratio (higher numerically) and gain better starting line launch (learn starting line technique better) at same time.

 

wow i had no idea it would cost so much money for posi. perhaps i'll just invest in the 14's, i'm sure that will do enough for what i need. probably a lot cheaper too, as far as the color. i've decided to keep it stock for the authentic look, as well as the financial reason. thanks guys

 

did ANY v6's come with posi? and how would i know if a thirdgen had it in?

 

ok i got mine for a trade. i got a slp take off and richmond gears. called a place and they quoted 325 for bearings and install kit and install. not to bad. or you could just get an entire rear off a 4th gen car and bam! posi and gears and rear brakes.

 

Our V6 have the better gears (3:42).
One need adapt "somethings" for a Fourth Gen axle assembly "AS IS" to fit our 3rd Gens.
Give a 14" tire set up a try & see if the results warrant the "cost". Ya should be able to find a 14" wheel for FREEE. Cost then is only tire! Find a super sticky drag racing type tire for best results. Mickey Thompson is one good brand.

 

I have a BFG comp T/A Drag radial and that sucker will not break loose once it is sticky. If i pop the clutch at 5000 nose lifts very high

 

V6 Thirdgens from 1984 - 1992 had 3.23 gears in the back.

 

I agree, not 3.42.

 

Seems majority here have the 3:42.
Maybe time for a new thread "what ratio you packing"?

 

Earlier v6 did have 3.42's up to about 89/90'ish.

Then it switched to "do you have auto or manual".

Autos got 3.23
Manuals got 3.42

If you go to main page of this site and look at the yearly info, it shows this.

 

That makes sense. I have auto with 3.23 gears.

 

So wait, I have a 5-Speed. I HAVE 3.42 GEARS?

 

I had 3.42's on an '87 2.8. I switched them down to 3.23's becuase they are much better suited for a 700r4. Especially when the 2.8 is putting out more than stock power. Hence why the larger motor cars when to even lower gears for pulling through each gear broader. For racing, go up. But for daily driving and all around higher speed use (freeways), go lower.

 

are gears different than a posi unit? or if i found a car that had a posi unit would it be switching gears too?

 

See any Hot Rod or Car Craft or any car magazine
but yes
A DIFFERENTIAL (in this case of discussion, posi unit) and GEARS (3:42/3:23)are two different items HOUSED in the rear axle assembly!

 

I have an auto with 3.23 gears. To be honest with you guys though, on the street my BF goodrich don't really brake loose unless I run up to about 2500 rpm half petal. Once I heat them up, I imagine they should grip even better on the track. Well, I have to run the car first at the track to even get an idea of slippage. I'm really hoping for mid to low 16's for my first run in this car. I had an oldsmobile alero which hit a 15.7 completely stock. I couldn't believe it, so i'm hoping for similiar results with this. If you look in the street racing posts i ran a 3.4 95 camaro, anybody have any ideas on times with them? We were pretty much on a dead heat until 75, so I imagine times will be similiar.
