Here it is.

Mine is 6000lbs. The denali shouldn't be any heavier than that.

 

I think the factory rated it at ~5400lbs.
The TBSS is only 2wd and is the base version (cloth, not many frills). It should come in around 4200 from what I have seen.

 

I have only made 1 weak pass with this motor in a different car. An 1/8th mile run on street tires. I only was able to pull in third gear.
2.25 60', 7.95@95mph.

I have a couple more mods to the motor and the 68 vette it is in now is setup 150-200lbs lighter that the car that made the run.

I'll get one shot at a track before they park me. I will take it to the 1/4 mile this fall with drag radials and more gear than before. I just have to make the first one count.

 

IMO...get rid of the duals and xpipe. go back to a 3" y pipe with single 3" pipe, and get your torque back. been there done the duals.

 

Sounds like fun car!

 

6.0's don't have a Y pipe from the factory. True duals to the muffler then 1 single 3" out.
