Damn that 6.2 looked like it was holding off that fast lightning too. Looks like you need some more go fast mods.

 

nah that aint gonan happen lol when im dont with the 5.3 in goes a 6.2 ...

 

what u guys think i should do next ?

 

heads brotha!!

 

Well with the new stall your probably running 13 flat or faster. The only thing besides more cubic inches is some lower gears....4.56s

 

Turbo

 

new stall huh?? what size did you get???

 

went from a stock converter to a circle d 3,200 single disc

 

i guess you didnt catch the second run with tbss vs 6.2?

and the first tbss vs mesrt is stock with just a tune.

 

Yeah dude, get the 4.56's!! My truck pulls dam good with them. My buddy has the exact same setup as I do except in a 77 GMC with 4.10's and 30" tires. My truck with the 4.56's and 28" tires, is dead even with his from a 20 roll in first and 2nd but pulls hard on him when he shifts into 3rd, and my truck weighs 440 pounds MORE than his!! Even right as i shift into 3rd and he's still in second, he never pulls on me. We haven't raced from a dig yet cuz I don't have enough traction but if we did I'm sure I could pull on him out of the hole.
