BIGLKNM Small-Block Chevy Bolt Kit — 211-Piece Stainless-Steel Fastener Set for 265–400 V8s

BIGLKNM Small Block Engine Bolt Kit is a complete 211-piece stainless-steel fastener set engineered to replace all major external and accessory bolts on Chevy small-block V8s from 265 through 400.

If you're rebuilding, refreshing, or maintaining a Chevy small-block SBC (265, 283, 302, 305, 307, 327, 350, 400), this bolt kit gathers the commonly replaced screws, studs, and washers in one corrosion-resistant package. Each component is stainless steel, precision-polished, and supplied in quantities matched to typical assembly needs so you can finish an engine exterior without scavenging hardware from other projects.

Which Chevy engines and applications does this kit cover?

This kit is designed specifically for classic small-block Chevy V8 engines and fits the wide range of displacement families listed. It targets exterior and accessory fasteners rather than internal fasteners, making it ideal for intake, exhaust, accessory brackets, and timing components. Verify individual bolt lengths and head types against your engine before installation.

• Compatible models: 265, 283, 302, 305, 307, 327, 350, 400
• Includes hardware for intake, exhaust headers, oil pan, valve covers, water pump, timing cover and more
• Best suited for small-block external reassembly and accessory replacement

What materials and quality controls are used so these bolts last?

All fasteners are made from stainless steel for improved corrosion resistance compared with plain steel hardware. Each bolt and washer is polished and cleaned to remove polishing residue so you receive ready-to-install pieces with a consistent finish. Threading is manufactured within tight tolerances to provide good fitment and grip without excess burrs or misalignment.

• Material: stainless steel construction for rust resistance and durability
• Polished and ultrasonically cleaned to remove residual debris
• Manufactured to a standard size tolerance of ±0.005mm for consistent threads

What specific parts and quantities are included in the 211-piece kit?

The kit bundles the most commonly replaced external fasteners so you can rebuild the engine's exterior and accessory systems in one go. Quantities reflect typical needs for a full small-block external refresh and include studs, bolts, and washers grouped by application. Use the included counts to plan which items you might still need for rare variations or aftermarket components.

• 211 total pieces: bolts, studs and washers
• Selected counts include header bolts (24), intake manifold bolts (24), oil pan bolts (36), valve covers (16), water pump bolts (30)
• Additional items: distributor screws (3), coil bracket (6), carb studs (12), crank and fan pulley bolts, fuel pump bolts, thermostat housing, timing cover hardware

How should I use this kit during reassembly and what should I check first?

Before installing, compare each bolt head style, thread pitch and length to the original fasteners on your engine and to any aftermarket parts. Torque values and gasket surfaces must be confirmed in factory manuals; this kit supplies hardware but not torque specs. Use thread locker or anti-seize where appropriate for your application and follow torque sequences recommended for each component.

• Match bolts to original locations by length, head type, and thread pitch
• Confirm torque specs from the engine manual before final tightening
• Use anti-seize or thread locker as appropriate for aluminum or steel mating surfaces

Who is this for: The BIGLKNM Small Block Engine Bolt Kit is aimed at home mechanics, restoration shops, and performance builders tackling Chevy small-block rebuilds or exterior refreshes. It suits anyone who wants a comprehensive, corrosion-resistant set of replacement hardware for intake manifolds, headers, covers and accessory components without sourcing dozens of individual fasteners. If you have a nonstandard aftermarket accessory or need OEM-specific head styles, double-check fitment and keep a few factory pieces for reference.
