Ok, last time out at the track I ran 11.96 and several 12.0x's-12.1x's with low 1.7's to high 1.6's. Front end needed to be tightened up as it would unload the rear tires about 2-3 feet out once the front suspension maxed out. This was with 428rwhp, weighing in at 3,840. Here are some things I have changed:

Swapped to a race style EWP
Went from stock LS6 to a Super Victor with carb style TB
Swapped to 4.56 from a 3.73
Taking about 350lbs out of the truck
Different shocks in front to hopefully negate the previous issue

There is no power steering, ac. Not too many places to easily shave weight. Any thoughts? Think it might make it with the above changes?

 

when my car was unloading after it hooked off the line i got a rear drag bar and it really seemed to help alot...front shocks didnt really help much....i know you have a truck though so it might be slightly different

 

I forgot to mention that there was a large rear anti-roll bar going in as well when I c-notch the rear frame. Thanks for the input though..
