Okay here's the deal, I'm planning on dropping a 393 in my 88 T-Bird. I have an Eagle rotating assembly, Cast crank, I-beam rods, and 273CP Speed Pro pistons (10.8:1). They're going in a 72 block, .060 so i believe that makes 399, using a custom grind 300 duration flat tappet cam with .540 lift, and a set of 190CC aluminum heads topped with an RPM Air Gap and a 750 Holley. I'm wondering if one of you guys could give me a general ballpark estimate on my power output. It would be greatly appreciated. Also I'm not real sure what to do with the fuel system to switch from EFI to carb, upgraded pump with a pressure regulator or what? Thanks guys! Also if anybody has a good C4 in Minnesota they're looking to get rid of, I need one..... Thanks
