The FE manifold family uses more than one bolt length depending on which casting is fitted, and mixing them up means either a bolt bottoming out or too few threads holding torque. This is the 3.0 in. set for the 2936 and 2937 manifolds, grade 5 steel, so the intake clamps down square without hunting through a coffee can of used hardware.

Edelbrock 8536 Manifold Bolt Set Specifications:

• Grade 5 steel bolts with a silver finish.
• 3/8 in. thread diameter, coarse thread pitch.
• 3.0 in. length.
• For Ford FE applications using 2936 and 2937 series intake manifolds.
• Sold as a set. Verify your manifold casting number, since FE manifolds differ in bolt length.
