any truck that can almost hit the speed limiter in second gear has too high of a gear. i've driven both a 3.42 and a 4.10 geared version. it's deffinitly noticable and once you begin to mod it, the results will be even greater. your rpm at a 70 cruise in something that big and heavy with that few cubic inches doesn't need to be below 2000rpm.

 

Who wants to get together a parts list to swap over to the 05 front brakes? Master cylinder, proportioning valve, booster,..... I wonder if you can get the old rear discs to work with the new fronts. Which proportioning valve would work best?
Inquiring minds need to know.

 

The new brakes are designed completely by Bosch, not GM. Literally EVERYthing is different. Taking the differences in volume and pressure between the two systems which has to be vastly different, I don't think the newer calipers would receive a proper feeding from the old GM-design master cylinder and booster. The rears would be a proportioning nightmare.

 

Nothing new other than the aluminum here. I'd like to know the new cam specs though.

 

you might ask one of the GM mechanics or workers on the site about the exact motor differences i remember stupidfast told me what they were but do not remember exactly what the difference was other than the 10 hp

 

interesting

 

they also have a "lifetime" in-tank fuel filter. what's the new cr? actually... what was the old 03-04 cr?

 

 

Where did you hear they had the LS6 heads?

 

This has me baffled. In the press release they claim that a smaller filter can be used with the returnless fuel system. So I guess if you have a truck with the returnless fuel system the fuel dispenser at your gas station senses it automatically and gives you fuel with less dirt in it! Of course! Stupid me...

My 'Hoe hit 62K this month. I'm on my FOURTH fuel filter.
