did some more research for the 1995 z28 with p vin I have ,it says 3.23 gears I guess there can be more ratios depending on VIn #,it feels geared higher then 2.73 ,some have 3.43 this with automatics ,so mabey I got some bad info the first time ,the info I got now is supposed to be from Gm,also did not know there had governer to 110 miles per hour ,with governer removed top speed ls 155 lt1 ,so I would imagine ,with the 406 could be like 175mph ,though I am not going there anytime soon ,I allways wondered though with the lt1 why it said 110,couse govenor

 

try raising the rear and turning the wheel one revolution while at the same time count the revolutions of the drive shaft. make sure the other wheel is turning the same direction. open center section will allow the other wheel to turn the opposite direction and a shot posi most times will not turn at all. if the driveshaft turns 3 and 1/4 times or there abouts its a 3.23.

 

thanks craby will try that next time on lift ,wich will be soon ,not to get off subject ,my friend has the 2015 challenger 392 shaker hood rated at 500hp 8 speed tranny ,I guess the only difference is the money his cost $43.000,i wont tell him I think he spent to much for braging rights 185mph track ready ,an probley govenred there to ,I am kinda kicking myself ,there is a 74 z28 on ebay right now that was a drag car now pro street ,with a fresh 383 ,leather inside the car is a full resto ,new paint 456 Detroit locker ,an the kinda set up I want one day ,looking back this car $7995,00 guy has 100% feedback an if the pictures are as true as when I bought the one I have now what a deal ,only thing I see needs upgrade is to serpintine belts pulleys ,I wish I had the money ,I would drive out an look at it ,its a sweet car yellow an black,but to compare the 74 to his ,just as ready for the track ,I got to say what a buy ,but not all guys are looking for a prostreet car I could love it looks mint an new ,so I guess I would raher own 2 or 3 old ones then one new one an for less money to ,if you shop there are some great deal out there

 

couple years back i had a line on a ls1 6 spd camaro for 5k just bought stuff for this one so couldnt come up with the cash fast enough.

56,000 miles few pics bad but can see the whole car is like even has sunroof

 

yes it does bother me to think I could have that for less then what I put in my in the last year ,but live an learn ,no matter wear I go this is the look I love the most ,surprised not sold ,but not all are looking for prostreet ,no fender wells ,everything is desiged to make it lighter ,an the engine has some good stuff to much to talk about auction ends Monday in PA,i see why the guys put big blocks in the older ones ,some much room for a big block ,get a chance look at it

 

Vin won't tell you gear ratio. No automatics came factory with 3.42s. If your Speedo only goes to 110, then your gear ratio factory was more than likely 2.73. You can verify this by looking at the shifter selection. If 1st gear isn't labeled, it was a 2.73 factory. If it is labeled, chances are it's 3.23. Example: with 2.73s it'll read PRN-OD-D-D2, with 3.23 it'll read PRN-OD-D-D2D1

You car with either gear set, governor or not, will probably top out at 150ish if you had the room to go that fast.

 

the info I got was that the lt1 was governed ,not my 406 ,an from gm the gear ratio is 3.23 for a 1995 automatic ,feels like it ,273 seems would be very hard to chirp 3rd ,actually I am ok with the way thing are ,I just relize I have a 20 year old rearend that I changed the gear oil in 2 times since having it will need to be replaced the gears ,will have to check it though

 

Your car may not be governed, but chances are you car would run out of HP or gearing long before it hit 175 mph. Not all 95 were 3.23s. 2.73s were possible through out the entire fourth generation. Like I said though, every V8 fourth gen I've seen with 110 mph speedo and no 1st gear labeled on the shifter was a 2.73 rear.

 

What was the mpg difference in swapping from 2.73 to 3.42? I'm thinking of swapping out my 3.08 diff since I drive in a lot of stop and go traffic, not to mention I like to go after imports on side roads every now and then.
