2007 silverado 4.8L 2x4
212/218 on a 114 cam
shorty headers
punched out cats
cold air intake
flowmaster dumped b4 axle
truck put 290hp and 265tq
what are yalls thoughts on those numbers, wanting to get around 350hp with the 4.8
soon to come long tube headers

 

I hope you mean 212/218 cam??

 

yes i ment 212/218 nice catch im hoping the long tubes wil boost it up a little bit

 

Headers and a good exhaust should net a 20hp gain.

 

what do you mean by a good exhaust? im gonna throw a 100shot at her soon thatll wake her up

 

Free flowing with the least amount of resistance... Like mine, it dumps under the front passenger seat

My truck made 355/386 on a dynojet with headers, CAI and a 50shot.

 

Wow your putting down quite a bit more then me , that has to be so loud with no muffler and dumped under the seat

 

That's the numbers on my old setup. It should make around 450-460 now still stock cam.

Its loud outside but not to bad inside. Every girlfriend has loved it so I guess its the perfect exhaust setup

 

Here's to give you an idea. Just LTs/50shot vs cammed, stalled rcsb silverado

 

Is that still a 50 shot
