went to the track last night and i made a few passes in shackattack's 6.0 with vmax heads and cam well he always had problem hooking trhen he put the bars on and the new 27" mt dr for the 17" rim and i could not get them to spin i was running with 26lbs of air in the back and was leaving off of idle and it still would not spin not a hint if spining nothiing it would pull the motor down in stead of spining.we are going to work on the timing down low and put a 3800 pi in it and see what is going to do.

oh yea by the way 07 max with full stret trim ran a 14.51 just like i drive it everyday.

 

Good to hear. What settings did you set them at,curious.. What they spec'd ??

 

What were the 60's and MPH?

 

4* pinion angle what ever ones for the truck it only has a 2" drop in rear.


it was running 1.60 now we are at 1.73 for a best it is really bogging the motor down, i could not belive it.

 

they are working very good for me

 

glad youve had better luck with them than i have...

 

i pulled a 1.62 with them this past Sunday.

 

My best 60' has been 1.52

 

how are you guys setting them up? maybe its my extended cab killing me???

 

From what I hear, Calvert presets them for whatever you told him they are going on as far as the top and bottom holes. Unless there's another trick..
