question on hwy cruising

the exact specs on the motor are .040 8.7-1 pistons head is milled .020 to clean everything up using a holley 350cfm carb comp cams 264s cam (264 duration 220 at .50 1.6 rockers should put me at .477 at the valve) and a 2 1/4 exhaust havent decided on muffler yet. honestly im sure the desktop dyno is a best case scenario but im shooting for 150 and 220 N/A. im thinking next year it will have a mitsubishi 16g hanging off the side with 8psi of boost. then il be shooting for 210 and 300ftlbs :burnout:
