Irwin's car has a non-intercooled vortech kit making 11psi with a rather larger pulley. He is using the 90MM Lightning maf, 42lb injectors, and focus fuel pump. The car could benefit from a fuel pump wiring upgrade back to the FPDM. It also has cams, TB, and plenum. The engine previously made 263RWHP NA.
