I plan on adding cam/valvesprings/headers/ORY/tune within two weeks. Will I be able to compete against the mighty 8.1L when it comes to towing? I keep hearing I should have looked for the 8.1L instead of the 6.0L for towing.

 

what are you going to be towing

 

Yes, my dads 8.1L doesn't tow that great. So with your mods you will probably tow better then a stock 8.1L.

 

I only plan to tow my Supra or my Vette to track events. In the future probably more..

 

The allison is what makes the 8.1 trucks so great.
As far as the engines go, with the right cam you should be able get up to speed quicker than a stock 8.1

 

You'll be in the same ballpark. Once you get the weight rolling you'll be just as good.

 

What trans is behind it??? 80E?

 

Have to be wouldnt it?

 

maybe the manual?

 

The allison robs a lot of torque away from the 8.1L. I would take a 80E behind the 8.1L anyday. A Duramax and Allison make a great combo. We have owned both combinations, and the 8.1L with a 80E seem to have a little more get up and go then the 8.1L Allison.
