What type of rear end does it have? Its 2wd correct?

 

Wow!!

 

The rear is stock. We broke the locker first pass. We pulled it out and welded it up. After the 9.27 pass, we gave it a little more. Broke the axle. We are waiting for some axles from Mark Willaims. Trying to put it in the 8's.


Thank guys, it was a fun project.

 

Very Impressive.
Build Sheet?

 

Wow... I had no doubt you guys would get that thing solidly in the 9s but knocking on 8s?!?!?! impressive just doesn't do it justice.

 

Sounds like a good application for a Detroit Locker to go with those axles. Am I correct that it's a 7.0L running up to 7400rpm?

 

nice time really nice times! what is the run down and i know you are sparying a dry shot but how much,and when.i was told that the trailblazer was 4 link,i am not saying it is i was told this please correct me if i am wrong.

 

The truck has a 427 LSX, 2 stages wet, stock style suspension which is considered a 4 bar setup not really a 4-link, stock rear end with detroit locker, 4,625 pounds with driver, full interior and full cage.

 

so its a 8.5" 10 bolt? Do you think with built axles and maybe a spool or beefier differential it'll suffice? Or is the ring/pinion - housing design flawed for such an application?

 

Pretty sure those came with 9.5in 14 bolts
