1966-1968 Chevelle Master Engine Bolt Kit, 283, 327, 350 with out AC, The 1966–1968 Chevrolet Chevelle Master Engine Bolt Kit for small-block (283/327/350) V8 configurations without air conditioning is a concours-correct hardware kit designed for authentic factory restorations. Manufactured primarily by AMK Products under part number EFK341 (and widely distributed under SKU MEK66SBS), this kit contains 152 pieces of period-accurate fasteners.

Unlike the A/C-equipped variant, this kit features standard accessory-mounting hardware and specific exhaust manifold fasteners that lack the specialized extension studs or clearance offsets required for factory compressor brackets.

• Authentic Head Markings: Fasteners are designed to meet strict classic vehicle judging guidelines, matching the original GM assembly line finishes (such as gray phosphate or specialized zinc plating).

High-Visibility Stainless Steel: High-exposure external hardware—such as the valve cover bolts, valve cover load-spreading retainers, exhaust lock bridges, washers, oil pan bolts, and timing cover bolts—is constructed from stainless steel for enhanced durability and corrosion resistance.

Labeled Sub-Kits: To prevent confusion, the 152 pieces arrive organized into individually bagged and indexed groups corresponding to their placement on the engine. Sourcing this bundled kit typically saves 25% to 30% compared to buying fastener groups separately.
