LS swap

[hoagster]

I also went 6.0 LS with 4l65e from an 04 Escalade. Did all of my own work. You can see my thread below.
As mentioned before you will need to find a t-case (np241c) and gauge cluster from a 90-91 Blazer/Sub.
I also use a 90's 6.5ltr gas pedal since I have DBW for the factory look.
Mine is a full restoration, finishing my interior now.

The big question would be, which is easier...

Hands down, pull the old sbc and replacing with another.

Need help finding a suitable sub for the electronic gas pedal any ideas

If doing DBW then the 95-2000 Silverado 6.5 diesel, you will need to switch some pins around or buy a reworked pedal to tac harness (will need to know which model TAC module you have as well). I went with one reworked and it was $50-65 to my doorstep. Lots of videos on the web on this.

If you are going DBC then I've read that the 2008 Silverado throttle cable is the right length and will clip into the stock C-10 pedal. I do think you have to trim the clip at the firewall a bit for it to fit the stock C-10 hole but its minor trimming on plastic. Lots of videos on the web of this.

Thanks guys, I found what I needed, they make a pedal now C=10 OBS that bolts right up, and you can also get a 72 inch harness so you can mount the tac module with the ECM.
