4.10. Got a STOCK 8.8 out of an explorer with factory 31 spline axles and stock gears. Running 26" tall tire.

I think the truck is slow quite frankly lol. But I guess that is because many of my friends are in the 5's or very low 6's to begin with.

 

Those are the same gears i run. Anything that runs in the 7's in the 1/8 and is a street vehicle is pretty darn quick.

I have almost same stall as well. My truck must have a few hundred pounds on your Blazer.

I think the 4L80E eats up some power as well.

 

From what I have read here and other places, YES, the 80e does consume some more power.

What tires are you running on your truck?
