[Big Buttons]

BigButtons... Isn't that stall for a nbs? He has a nnbs... Correct me if I'm wrong please cause I'm looking into a stall for my '11 nnbs. Thanks!!!

Same trans in the NBS and the NNBS. Except the 6-speed of course.

4L60 LS style High performance. 300mm is for the lower stalls 278mm is for the higher one's. I have a 278mm 3000-3200 waiting to go in.

your better off swapping it to a 5.3, call texas speed for a "package" and you will be happy for atleast a week till you want more.

+1 The 4.8L are discontinuted and getting hard to find. We had a customer come in with a 4.8L that he threw a rod in. It was still under warranty but we just couldn't find any crate motors available through GM. I think we did end up sourcing one from another dealer but it was a fiasco that took way longer than it should have.

^ Agreed.

I know it seems like a monumental task to do an engine swap, but if you're set on spending the time and money on a forced induction setup, get the 5.3 dude. You don't have to spend major cash on a crate motor or anything - there are scads of long blocks that can be pulled from wrecked trucks pretty cheap if you have a couple buddies and a weekend. More work? Yes. Worth it? Absolutely. The 5.3 isn't going anywhere for a good long time, and even if/when it does, they are ABUNDANTLY more common than the 4.8, make more power, and if you remove AFM they are stone reliable even with FI.

If you're just gonna do bolt-on's (cam, headers, stall, etc) then keep the powerplant you have....but if you're gonna be neck deep in the front end anyway to install and plumb a turbo kit, might as well do the swap. Just my two pennies.
