i just bought the new silverado with that slow 4.8 i have a couple of question i thought of the 408 setup but the problem is i have no idea what to do to get that setup? the other thing is what numbers do you guys get with that setup with and without forced induction?

 

use the search feature cause the answers to your questions could fill a thread bigger than grippy's

 

Search button. Look up a member named Quik. He has a N/A 408. There's another truck too but I forgot his member name but he's got a thread going right now.

 

This could be answered easily depending on if you want to buy a crate 6.6/6.7L or build your own. I'd suggest going through Wheel 2 Wheel or Scoggin Dickey.

 

Other member's name is Flyer I think.

 

use search and look into threads. this is GM trucks bible!!!!better then manual and dealer.

 

thanks a lot guys for your help i`ll be searching right now and i`ll post any progress

 

Call Scoogin Dickey and get one of their forged 408s... There are very nice, tight motors.
