Doing a similar setup LQ9 408 twin turbo with 317 heads. Sound crazy but I'm going to try to make between 1000-1500 hp at around 24-26 psi. when I first I was going to use the gt45 Ebay turbo, but after reading Hot Rod Magazine I changed my mind. I going to use two CXRacing 76mm BB turbo priced around $600 each. If you get a chance look up Hot Rod Magazine project named "Big Bang Theory" and keep in mind that it's a 4.8. I started work on a shave truck intake and stream cross over tubes on the heads for #7 cylinder. Post some pics soon.
