I appreciate the offer. I went back and forth between 4.56 and 4.30. I drive 6 hrs to work and 6 hrs home every 2 weeks so that's why I decided to go 4.30.

I sure hope so. Would love some low 11s with the 70mm but we will see.

OK so which gears do i need?
Motive G885430 or GM10-430?
Best i can tell the difference on G885430 is the pinion in this gear set will accept the factory ABS reluctor. Soo is that what i need?

Ok, so I have decided to leave the 3.42s in until i get it boosted and see how it does. Going to use that money to buy oil pump, lifters, timing set, etc(replace the worn parts) and install cam. Hopefully it will be going on the dyno in a few months! I want to pickup another engine for when this one blows. Having a hard time deciding on another 4.8 or 6.0... I will also be upgrading the turbo when i do the engine swap as I am looking for around 700rwhp+ . Basically there are several mid-high 10sec cars that i would like to play with. My brain says get 6.0 and make power but my wallet says there are plenty of people pushing power on the cheap 4.8s(already have a spec'd cam)??? SOOOO get a 4.8 or 6.0/spec'd cam??...

A 4.8 always adds a little cool factor to it. Specially when you hand them their *** and your rocking the little LS that could lol

So, I'm pretty much down to just turning wrenches. I want do everything and get it tuned 1 time. That being said I want to upgrade from the on3 70mm turbo. I have 2 that I'm really looking at, the tried and true s475/83 T4 and the new s369. I'm looking to make 700+ whp on the 4.8. Not really to worried about numbers I just think that's where I need to be on high boost to play with a few buddies rides. Also if I can achieve the 700+ mark without having lag on the Lil 4.8 I will just stay with 4.8s as apposed to 6.0 swap. I'm thinking the s369 will be great on the street for the 4.8. I'm just wondering how far it will take my cam only 4.8? Mid-high tens?? How much boost will it effiecently support? 20psi?
