Hey, i am looking to put a 408 in my truck. I have a 99 silverado with the 5.3L now. I already have ordered the turbo system from sts last week. I have been unable to find a store/someone that could build me a 408 that could handle some boost. I tried going to latemodelengine.com but the website is down or something. If anyone could refer me to someone it would be great. Thanks in advance.

 

you might find more info in the GM section

 

I believe some of our sponsers sell short blocks.

 

I believe that SDPC will build you a long block.

 

What turbo did you order from sts? They have a dyno sheet of a 408 with a pt-88 making 900lbs of torque!

 

You must have money falling out your ***.

 

all i ordered was the base kit, intercooler, blowoff, nelson tune, and boost control.

 

NO DOUBT.

 

I dont think the base kit with the t-60 turbo is going to be enough to run a 408. The 6.0's use a gt67. You many want to upgrade to atleast a 72!
