Quick question. I have a 06 silverado cc and a buddy of mine has a 08 single cab. Both of us have an exhaust and that's it. We are gonna race this weekend but just out of curiosity has any body here raced a set up like this either having a nbs or a nnbs against each other. I'm just curious.

 

Should be all him you should be about 600 pounds heavier

 

get it tuned and you will beat him

 

He has more torque management, but he should still take you.

 

X2 otherwise he will take you lol

 

Thats pretty obvious the reg cab is faster. plus his engine has better heads and intake.

 

1) You have a crew cab, heavy as **** in other words
2) He has better head and intake like said above
3) I would beat you on foot lol

 

Just curious, by better intake do you mean the airbox & filter or the actual intake that goes over the engine? Is there a benefit of installing this heads on a NBS 5.3? I think I could get them for cheap from a good friend.

As for the question, the NNBS are faster, torque management and all plus it's a RCSB.

 

Yes the intake on top of the engine is better and bigger, 90mm. And yes the heads off nnbs are 799/243 heads, the same that came on ls6 vettes.

 

It wouldn't be worthwhile to put those heads on a nbs unless you got them milled... They will drop the c/r on a nbs 5.3. If you got a set and had them milled and ported it should be very worthwhile and do a 90mm intake while your at it
