How fast have you gone? I have been 15.3 at 94mph. Stock with a tune and no muffler. Just curious, because it seems this gmt900 section is full of 6.2 bullys with there gobs and gobs of power... Im hoping to purchase longtubes and an intake this summer. Gonna see where that puts me. 4.10s would help this slug out too. No i am not swapping in a 6.2! Although it would fly

 

Bout time someone with a smaller engine thats letting them hang!!!! I now my cusin which isn't a member on here is running 12.20s on his 5.3L but is a RCSB i'm sure high 12s with a ecsb or ccsb

 

My brothers cc trucks got a 5.3 w/six speed t70 running 11 pounds. Its a whole different beast. Been meaning to run at the track to see what it runs but time dont allow.

 

Hell yea! im hoping low 14s with bolt ons and a good gear.

 

Mine is a slightly bigger 4wd truck but I've gone 15.44@89.5. Based on your mph that 2wd drivetrain is really helping. I had too much wheel hop launching in 2wd and didn't try switching out on the big end. That run with the wheel hop did gain me over a mph though, so I am sure that I could launch and switch and get a better time.

 

That's a good time for a big 4x4 crew. And I was quite shocked by the 94mph as well haha. I think my 3.08 gear helps the mph. But I wouldn't mind sacrificing mph(gear swap) for a 14 second slip.

 

Unfortunately my truck still isn't as fast as a ccsb 4x4 with a 6.2L stock. My dad bought one and smoked me basically on the day he brought it home.

 

ya hell with the 6.2L put a 7.0L in it NOW GIMMY YOUR GAS MONEY

 

I'll just trade your tvs for my gas money??? Eh?

 

all i have to say is read this:

new era is running faster than some 6.2's and is still adding on the power.
