E85

Can I start running e85 in my car or do I need a tune ? Not sure if the stock injectors or fuel pump can handle it. The best fuel we have here is 91 Octane otherwise, and from what I hear, e85 will also help with heatsoak.

I have a rotofab on now, but will be installing a 9.55 or 10" lower along with ID850's and a tune next summer.

On a stock car, the injectors and pump should be fine with E85. You should still datalog or put the car on a dyno to verify.
But no, E85 doesn't affect heatsoak at all.
Modded....needs a tune and more pump.

With the mods, would the boost pump work, or would the original need to be replaced ?

I'm thinking replaced. Almost positive of it.
Here's the thread that smokum was referring to: http://www.camaro5.com/forums/showthread.php?t=274664
Andy should be able to help you with getting the right parts to go E85 on your ZL1.

Imagine this fuel system setup and install with ID1300 injectors and a flex fuel conversion and tune. Expensive, but all the E85 fuel anybody would ever need and it would automatically adjust to the change in E85 mixtures throughout the year without needing multiple tunes.

If E85 were more available where I'm at I would already have had Andy done this. Closest pump to me is 30 minutes.
