Edelbrock 7166 Performer RPM Intake Manifold Bolt Torque Sequence Diagram

This document is a top-view line drawing of an Edelbrock Performer RPM intake manifold, casting/part number 7166, showing the recommended bolt-tightening sequence. Sixteen circled callout numbers (1 through 16) are arranged around the manifold's perimeter, indicating the order in which the intake manifold bolts should be tightened — starting near the center bolts and working outward in an alternating top/bottom pattern, ending with the outermost corner bolts (15 and 16). The manifold itself carries cast lettering reading "Edelbrock" and "PERFORMER RPM," along with runner/port numbers 1–4 on the upper runners and 5–8 on the lower runners, identifying the cylinders each intake port feeds. The drawing shows a dual-plane manifold with a square-bore carburetor mounting pad in the center. No torque values (ft-lb specifications), thread sizes, or year/model applicability statements appear in the image — only the bolt sequence numbering and cast identification markings. A reader can learn the correct 16-bolt tightening order for installing this Edelbrock 7166 Performer RPM intake manifold and identify the part by its casting number. The scan was uploaded to a 1979 Ford Bronco gallery, though the document itself does not state a vehicle application.
