We hit the 100 + hp per liter on pump gas

Very cool. The single plane intake obviously moves the RPM range up from the stock LS7 intake - a stock intake LS7 won't make peak power much past 6500, no matter how big the cam is. And 711 on an engine dyno is really screaming!

What EFI are you using again?

we are using the Panthera EFI . The stock LS-7 intake was ported a lot to make it work right, The two in spacer on top gave it almost 20hp. Wagner sells the whole package for about 18500.00 it comes with a wiring harness and Panthera EFI and front end assembly pullies, brackets, power steering, alternator its the same that DSE uses .Its really a good deal.
