you have a 34 gallon tank in the booger.

nice truck

 

thx.i got a hold of the dealer n they confirmed that it is a 34 gal tank.

 

you should be safe at 450hp, just a lift pump, and a transgo jr. will keep things together for quite a while being that its 2wd and not lifted

the LBZ is a beast, Nice looking rig

 

im gathering parts for my SAS now.why would 4wd make a diff?weight?

 

added stress on the drive train, with that much hp your gona do dammage if you start pounding on it in 4wd

 

Gauges First



NICE TRUCK BRO

 

You will love it!! Good choice!

 

422 miles on a half of tank, damn that is amazing. I have an 06 and can't even get that on a full tank.

 

he's probably got a bigger tank than you, the CCSB trucks have smaller tanks than CCLB
