I dont seem to be able to find many guys with Crew Cab gas duallys out there. I remember a guy on here saying he did not think they even made a 6.0L for my dually. I guess he thought the smallest was a 8.1L, but I still have the original stick on my 01 and it says 6.0L.

Kind of hard to mod my truck when I dont have good examples on what other heavy truck guys are doing..

 

What are your goals and objectives? Better mileage? More towing power?

With almost 7,400 posts on this site, surely you have some ideas of where to start?

 

yes ive seen a ext cab 6.0 dually, also same person had a 8.1 crew cab dually

 

my uncle has a crew cab dually 6.0

do what everyone else is doing with light 6.0s... youll be faster, not as fast as them obviously but what can you expect from a 6600 lb truck

 

Most of my post are from ls1tech. My goals with this monster is more towing power. I doubt I will get better gas mileage.

 

Info on Duallys is hard to come by. But a 1500 HD is pretty heavy too. You need a tune and a cam to start with. Here's a thread with a good discussion on cams with some dyno numbers to back it up. Steve Bryant posted some good info there.

 

Sell it and get a diesel!!

I'd do a small-ish torque cam and a Radix probably, or possibly even a turbo that would spool at a very low RPM. If you feel like swapping motors you could do a stroker, that would get you up there for towing power too.

 

Good thread!! Many good suggestions in there.. Including the OBVIOUS trade it in and get a diesel. The thing is my truck is paid off. Going diesel would require payments that I dont want.
