RCSB 6.2/unknown cam/3600 stall/3:73 slicks will get you a 12.44 (Daryn C)

yeah its easier to get a 6.2 in the 12s w an ECSB but does it have to be 4wd?? just asking i wish i had a 6.2 n my CC

I couldn't find any timeslips or video of his Denali at the track. I see a lot of street racing but thats all. Any links?

Remember, trucks are faster in Houston/SanAntonio for some reason. If you run 12s in PA you'll be knocking on the door of 11s in S.Texas.

What converter will work with the 6 spd? Been looking at yank and circle d but nothing really mentions the 6 spd.

You would have the 6L80 trans, we can definitely make a converter for you. I would suggest our 258mm 3000 stall multi disk. Drive good for street use and still have towing capabilities. But should flash high enough to get you the performance you need at the track. Let me know if you have any questions.

I'm running a 8.5x's in the 1/8 mile now, which converts to a 13.30 or so in the 1/4. I have the heavy (82lbs!) 20" wheels and LS-2 Goodyears, which everyone says adds about 3-4 tenths to your 1/4 mile ET, and a 3.42 gear and my AFR is nowhere near optimum (12.1 at WOT high RPM. My truck is also AWD, which tends to be significantly slower than the 2WD. My other mods are in my sig.
I am sure a 2wd 6.2 with some lighter wheels, a good cam, CAI, headers, convertor, a decent tune and some drag radials could easily run high 12's N/A.
I'm not sure if you will see that with a lift kit and off-road tires, though.

BTW: Yank does have converters for the 6L80E. I have that PT3200 in my truck. It took about 2 tenths off my 60'. It's a little bit loose for everyday driving though, IMHO.
