Hey guys tryin to get my plan together for when i beef up the drivtrain to allow for more boost.

Do you think that stock 3.27s will hold up in a built rear end w/ 31 splines? Or should i get an aftermarket set of gears (3.27s or 3.55s). Just asking because i have my stockers in my garage and if i could save from buying a set that would just be more $$ in my pocket!

So you think aftermarket 3.27s are stronger than the factory 3.27s?

I didn't know if they were made with different materials or not...lol figured id ask.

And my stockers have about 90k on em so i didn't know if that would have an effect on the life of them in a built rear w/ 600 hp runnin through em.

You'll be fine

Your sig says you plan on turbo-ing it later, I would definitely go with a set of 3.55s

Ok and how much different would the 3.27s perform then the 3.55s on the street?

I cant answer ur question dirwectly about difference between 3.27 to 3.55s but i when from 410s to 355s with no regrets.

negligible difference, especially with the snail

I think with a turbo there might be a bigger difference than you think. Turbos love load and 3.27s would load the turbo more. If one could tell a difference N/A between 3.27 and 3.55 I would think the difference would be even more noticeable with a turbo.
