There are quite a few companies out there now that offer a plug n play piggy back system for port injection like the weapon x kit comes with everything from the in tank pump to all the way to the injectors and fuel rails for your port intake set up. All you need to have is an intake manifold that will hold the fuel rails. The weapon x kit is $4,999.00 but there are other companies that offer the parts separate for less and you could probably piece together something for around $3000. Then you have to have the car tuned by someone that knows what they are doing with running multiple fuel systems. Also GPI offers on their site a triple pump or double pump set up from fore innovations as well.

The other option is the lingenfelter hpfp thats $1595.00, injectors $4399.60, and probably the LT4 low side pump would get you to where you want to be on E85. Maybe the LT4 with the addition of a boost a pump. I doubt you would need the additional fuel lobe from a cam seeing as how you are only trying to get to 700whp. There is a company that is selling the injectors for $900 cheaper than lingenfelter called fuel injector connection (FIC) $3520.00 over $1000 cheaper if you are or ever have been in the military as they have military discounts %5.
