#3821 Intake Bolt Kit

The EDELBROCK #3821 Intake Bolt Kit is a 12-point steel intake manifold fastener set engineered for Small Block Ford engine builds. This kit provides OEM-specification replacement bolts with cadmium plating for corrosion resistance, addressing a critical maintenance point that many engine builders overlook when assembling or refreshing fuel and intake systems.

The 12-point head design delivers superior engagement and reduces fastener slip during torque application—a detail that matters during initial assembly and long-term operation under thermal cycling. Cadmium plating provides environmental protection superior to bare steel, particularly important in storage or variable-climate operation where corrosion can degrade fastener integrity over time. The kit's compact dimensions (5.75 x 1.95 x 6.65 inches) and lightweight specification (0.79 lbs) make it easy to transport and store while remaining substantial enough to handle multiple engine configurations.

This kit is purpose-built for Small Block Ford applications—carbureted and early fuel-injected builds where original fasteners may be corroded, stripped, or lost. Engine builders, restoration specialists, and performance enthusiasts working on 289, 302, 351W, or related displacement variants rely on quality fastener kits to ensure proper clamp load distribution and manifold gasket sealing. Sourcing OEM-equivalent hardware from a trusted brand like EDELBROCK eliminates guesswork about fastener grade, plating specification, and head geometry.

Complete fastener kits reduce assembly errors and downtime by consolidating the exact number and specification of bolts needed—no mixed hardware, no substitutions, no risk of undersized or incorrect fasteners compromising manifold seal quality. The EDELBROCK brand's positioning in the small-block and performance market reflects decades of engine component development and OEM supplier relationships.
