Ok, when I went to the store this morning I ran into a Stillen charged Titan and he knew I had a whipple under the hood of my truck and asked to look at it and we began talking. It looks like it would be very easy to replace that blower with another roots type on the Z/G? Now that I'v compared two side by side it looks like it would be rather easy to do

 

Nike then!!

 

When you think about it. Whipple has a kit that replaces the Eaton blower on the Ford cobra and lighting applications. They are pretty much just replacing the blower and it has a plate that the blower mounts on. The stock fuel system supports up to 13psi before needing to be upgraded.
