Manley doesn't make cranks so I'm assuming you mean the Cobra crank? Also, I'd go w/ blower cams instead of run of the mill generic cams from Comp (Crower has some nice cams for this). In addition, for heads, there are better heads out there from Total Engine Airflow, Fox Lake Racing, and Steen Racing. In addition, depending on the amount of boost you're going to run (and ultimately the amount of power), you may not need the larger MAF or MSD coils. To add to what you listed, h-beam rods, Cobra oil pump, and built drivetrain (stronger clutch, trans, 31 spline axles and diff) to handle the power. Also, as a suggestion, you may want to upgrade the suspension and brakes to help put the power to the ground and be able to control it as well (such as RCLA, subframes, and Cobra brakes).
