But they aren't produced by GM, they are produced by Joe Gibbs.

 

Those Gibbs trucks arent exactly what I would call competition for a Lightning or SRT-10. They come from the (aftermarket) factory with a pressed on 5lb pulley and little else. You have to change the blower snout just to up the boost to anything decent.
Lightnings have HD rearends and trannies as well as stronger bottom ends. They can also put out like 13+psi on the stock blower Ive heard.
SRT-10's have built trannies and Im assuming pretty stout bottom ends as well.

 

There were 2 black Joe Gibb Silverados running at the track couple of weeks ago and the fastest time was a for one 14.6 while the other ran a best of 14.7. WTF? They ran several times and they were all in the hi 14s. They were real Joe Gibbs cus you could hear the magnacharger when they were burning out. They were running with the stock wheels. 20s? Oh they were both automatics.

 

Especially when my local dealer has a reg cab 4.8 for $44K

 

The Gibbs trucks are absolutely, ridiculously stupid in price. Get a Chapman SuperTruck if you're wanting to get a Magnacharger-equipped truck without putting it on yourself. Then you aren't paying $20K for lame wheels and 'designer fascia'.

 

Yeah, but if the aftermarket world ever catches up with you guys, I'm gonna hate to see that sticker!!! I don't think I'll have to worry about it where I live. Most of these guys look like the two guys on the commercial, only they can't afford a new hemi, so they just put the sticker on their old *** beater ram and hope nobody knows any better.
