i have a 2004 gmc sierra 5.3 ext cab 4x4. stock 3:73 gears on 16in rims 32.5 in tires... mods so far are CAI,Lt's with off road Y, Nelsons 91 tune, Ported TB, Tbss injectors, TR 220 cam on 114 lsa, vette servos. I was trying to get a guess at what my 1/4 time might be....

Tomorrow night ill be picking up some 706 heads, ported and polished milled .030 with a ported intake to match. I was wondering what you all think that would bump me too. hopefully in the next month or 2 ill have a cir-d 3000-3200 stall installed as well im shooting for low low 13's?

 

I believe...

You'll be close to, if not in the low 13's with the stall and those parts. That cam won't like those tires at all without the stall.

This is coming from a guy with no passes though. So take it with a grain of salt.

 

Haha NA that's what I'm guessing honestly. I would switch tires but its a 4x4 so maybe more gear? But the truck runs good already was jw what she could do

 

Shorter, smaller tires would be cheaper than gears.
that would help you out a good bit.

 

i may go the next size down but i just dont want it to look retarded, i have a leveling kit on it already so dont want to much wheel space

 

Without the heads and converter, i think you'll run mid 14's. With heads/converter, high 13's.

 

well i know i got a buddie that runs 14.1 in his truck and were bout the same everytime so id say im close to that right now i know andys running low 13's with a 6.0 gears and tbss intake and 3600 stall . my only diff will be a 5.3 3200 and maybe gears we'll see tho. im guessing mid-low 13's wouldnt be too bad

 

Big trucks need gear and converter to get moving, especially cammed big trucks. Where are you located, and what kind of DAs do you normally see?

 

This is true. I dropped almost 5 tenths going from a 3000 stall 278mm converter to a 3600 stall 258mm converter.

 

would i be able to town with that big of a stall tho? i was thinking 3200 stall and 4;30 gears? also i live in AZ and whats DAS?
