Has anyone here compared the performance of a Titan to an Avalanche 2500HD with the 8.1L vortec big block yet? I know the Titan is more powerful than the Avalanche 1500 series with the standard 5.3 liter, but how does it compare to the 2500 series with the 8.1L?

After searching the Avalanche forums, it seems they can have pretty respectable performance with some minor bolt-ons. However, I think the Avalanche 2500 weighs alot more than even the heaviest Titan.

If we assume the Titan puts out more like 320-330hp instead of the factory underrated 305hp rating, then it seems to be only the TQ which is alot higher in the big block Avalanche. Nearly 80ft.lbs of difference between the two engines!

5.6L Endurance...305hp/379TQ
8.1L Vortec...........340hp/455TQ
