25thSwappedRS

I have a 1992 camaro rs with an older 350 v8 swapped in. It was rebuilt a few thousand miles ago, was bored 30 over, has hypereutectic pistons, edelbrock performer 750 carb, edelbrock rpm intake, world product 2.02/1.60 heads, hedman headers, straight pipes with cat delete, 2500 stall, turbo 350 with a shift kit and ratchet shift. It has the stock 2.73 rear end and i want to change it to a 3.73. I'm a major noob when it comes to this and i don't know what i need to do the change, besides the gears obviously. Help?

I did much of what Ron USMC did to his 10 bolt (I added LPW Brace and solid pinion spacer).... at the same time I also switched out to Founders LCA's with 3 way poly joints.... yes, it was expensive, but due to all new parts, the car rides so much smoother / less harsh than before (like my Honda Accord)(I have Bilstein's and Subframe connectors, etc...)

My neighbor has a 89 305 TPI Iroc... 2.77 rear.... I gave him my old rear end... It was out of a 91 Formula 5 speed, 3.42, Posi, 28 Spline axles, he Loves it!

If budget is limited, get a 3.42 out of a 90 - 92... they have the 28 spline (stronger) axles, before then they had 26...

To go from a 2.77 to 3.73 you would need all new internals, since they are different series...

From a 2.73 with open differential to a 3.42 with an Eaton posi.

Every penny !!!!

Honestly i mean my camaro is fast enough to put down most of the cars on the street as it is... its fast. But it has not been tuned since it was rebuilt, it has a stock camshaft, and the stock 2.77 gears and open diff. People tell me to roast them and the best i can do is a unicycle burnout lmao.

On top of that the open wheel's tire is nearly bald. I cant imagine how fast this car could be if i change those few things.

I also have an MSD 6al box laying around here that i should probably install.

2.77? Do you have the 9 bolt rear end? If you do then that's completely different. You must be sure of which rear end you have before you get started on this.

Actually i'm not even sure anymore. The guy originally told me it had a 2.77 and i thought it was a 2.73 but now i'm seeing other things online. I'll just have to look when i get home.
