is your 4wd becouse the 4wd's have a one peice.

 

I have a rclb with a 4.8, and with out the 20's on and just my steel stokers I absolutly blow away my buddy's 03 hd2500 with the 6.0 in it. With my 20's I just barely pull away.
Now my truck vers my other buddy (rclb 5.3) mine just starts to pull him in the uppers.

 

Close call on the race, but I can carry more gear in my ex cab. Besides , whooping a stang in a ex cab gets more attention

 

Come on guys. Well all know 4.8's are where its at

 

Ya whats the matter guys,you forgot that the smaller the motor the faster you go

 

You're lucky that 4.8 hasn't blown up with the kinds of boost you pump into it.
My 5.3 couldn't survive 5lbs from the Whipple for 10 months. Get a 6.0.

 

My **** aint blowing up anytime soon. I hope

 

Has nothing to do with the motor size or type. It was a crappy tune that killed your motor or you did something bad lol.

My 5.3L handled 14psi for quite some time before I sucked up all the ater. hehehe
