1968 Chevelle Master Engine Bolt Kit, 396 or 427 With Aluminium Intake
1968 Chevelle Master Engine Bolt Kit, 396 or 427 With Aluminium Intake, The 1968 Chevrolet Chevelle Master Engine Bolt Kit for 396 or 427 Big-Block V8 high-performance engines with an aluminum intake manifold is a premium, factory-correct hardware pack engineered for accurate engine reassembly and concours restorations. Manufactured primarily by AMK Products under part number EFK345 (and widely distributed under vendor SKU MEK68BBH), this kit features 168 pieces of period-accurate fasteners.
This specific configuration provides the distinct, longer structural bolt dimensions and specialized flanged head washers required to safely mount a factory high-performance aluminum intake manifold (found on the 396/375HP L78 or 427 dealer COPO setups) without damaging or crushing the soft aluminum casting. It is also tailored to the factory short water pump setup utilized by GM through the 1968 model year.
Kit Specifications & Features
- OEM Restorations: All fasteners strictly adhere to original GM factory blueprints, offering era-authentic head markings (such as the distinctive “A” flanged heads for the aluminum intake) and factory-correct plating finishes like black phosphate-and-oil or zinc.
- Stainless Steel Components: High-visibility exterior fasteners—including the wide “TR” stamped valve cover bolts, load-spreading valve cover retainers, exhaust lock bridges, washers, oil pan bolts, and timing cover bolts—are made of corrosion-resistant stainless steel.
- Pre-Sorted Labeling: The 168 pieces arrive organized into individually indexed, application-specific sub-kits. Sourcing this bundled master set eliminates tracking down individual fasteners and saves over 30% relative to purchasing individual hardware groups separately.
