Ford 255/302/351W & 351M/400 V8 Intake Manifold Bolt Tightening Sequence

This scanned page from an automotive repair manual shows two intake manifold bolt tightening sequence diagrams for Ford V8 engines. Figure 2.47 illustrates the intake manifold bolt tightening sequence for the 255, 302 (partially cut off as '3') and 351W V8 engines, showing a top-down view of the manifold with twelve numbered bolt positions and an arrow indicating the front of the engine. The numbering starts near the middle-right of the manifold (bolt 1) and alternates side to side, working outward toward the front and rear. Figure 2.48 shows the corresponding twelve-bolt tightening sequence for the 351M and 400 V8 engines, with 'FRONT OF ENGINE' marked by an arrow at the left; the top row runs 7-3-11-9-1-5 and the bottom row 8-2-10-12-4-6. Both figures reference Section 37 of the manual. No torque values are printed on this page, only the bolt order, so the reader learns the correct sequence in which to tighten intake manifold bolts to ensure even gasket clamping, but must consult the manual text for the actual torque specifications. The page was uploaded as part of a document set for a 1992 Ford Bronco.
