2018 Callaway Silverado build

[cstmg8]

 

I'm finally getting ready to mod the Callaway. It's got about 11,000 miles on it now, so I feel I've at least broken it in and hopefully passed any worries of a lemon or big issues.

It's going to be a paced journey, but I hope to tastefully make it my own while maintaining most of the Callaway uniqueness.

My plan for the first round of mods are:
E85
Throttle body
Smaller pulley
Headers
Dyno tune
I figure this will put me close to the limits of the fuel system and transmission.
The e85 parts showed up today

My hope for this build thread is to get advice from those who are more experienced in modding these trucks, to prevent mistakes along the way.

BTW, the Callaway supercharger utilizes the tvs 2300 rotor pack and is there own triple intercooled design.

So... It looks like my blower has a 3.5" pulley on it, with the factory size crank pulley. I should have a LOT of room to grow, as the same blower on the sc757 Corvette is running a 2.65" blower pulley.

I would appreciate opinions from those running blown L86 engines on anything I need to do. Also advise on things like
Overdrive crank pulleys available
Best throttle body
Snout porting
Fuel capabilities
Etc...
