Pitt, Wish you had some Vids from the test... but as far as what I see on these runs is the truck bounces off the line.. look close and you can see it bounce a couple times right off the line.. Just a thought..

Exactly...that is why I was questioning the change of gears in my original post. I need to be able to stab the throttle from idle to get any gains from the stall.

Pitt, Yep, I was getting too that as well, just wanted you to see what I saw... Well, it's not a truck, but I had better 60's with my 3.42 than i did with the 3.73 So what does that tell you....Does not make sense but that's what happened... Now that being said, I did pickup speed in the 1/8 th with the 3.73's... 3.42 = 97.+ 3.73 = 100 but the car ran 10.71 to 10.75 with either rear.
So my thinking is that if you go with the 3.73's or 3.90's it should net a better 60 because you won't be spinning so bad off the line, you might lose some speed in the 1/8th but you would pick it back up on the big end.. That's jusy my take on it...
