Were they street 20's ? Or Dr's?

 

street 20s
it used to cut 2.0s on DRs or street tires didnt matter

 

Gears gears gear

 

Bigger cam needs more gear like bumpers said.
You are still on 3.42's right? Have you tried using a 28" slick?

 

On the 2.15 60 did it spin?

 

Grab a looser converter an itll roll out

Besides, i wouldnt worry about it....you didnt build the truck for the 1/4 mile, you built it for the roll....Right?

 

yea it spun on the 2.15 60ft
from a roll its i feel its stil lacking

 

what converter are you running? a decent converter would help from a roll as well. what size tire are you running? have you raced anyone from a roll that you raced before with the old cam? to get a reference to how its doing from a roll.

 

yank tt3000 stall
30 inch tall tire
the only person i raced from a roll changed stalls and he now pulls me before i could pull him a truck maybe alil more with my old cam

 

The right setup will get you where you need to be. The new heads & the bump in CR will make all the difference. It sure helped mine
