To complement its Performer RPM intake manifold, Edelbrock provided a pair of its Signature Series valve covers. They fit perfectly and kept oil leaks at bay. We topped the intake with an out-of-the-box 0779 Holley 750 Double Pumper. That's MSD's new Pro-Billet Ready-to-Run distributor powered by MSD's Pro Power HVC coil. The wires are MSD's Street Fire series, and we used Autolite 86 plugs, stock replacements for a 383 Roadrunner.
