1969-1972 Chevelle Master Engine Bolt Kit, 396 or 454 with Iron Intake (LS5), The 1969–1972 Chevrolet Chevelle Master Engine Bolt Kit for 396 and 454 Big-Block V8 engines with a cast iron intake manifold (including the factory LS5 454 configuration) The master kit supplies all exterior-facing hardware needed to mount secondary components back onto a clean big-block long-block

This package is specifically engineered to fit the lower deck profile and precise thread depths required for heavy cast iron intake manifolds, while accommodating the factory long water pump assembly that GM introduced standard across all big blocks starting in the 1969 model year.

• OEM Restorations: All fasteners strictly adhere to original GM factory blueprints, offering era-authentic head markings and factory-correct plating finishes (such as black phosphate-and-oil or zinc).

Stainless Steel Components: Visible, high-exposure exterior hardware—such as the valve cover bolts, load-spreading valve cover retainers, exhaust lock bridges, washers, oil pan bolts, and timing cover bolts—is constructed from stainless steel for permanent corrosion resistance and a clean appearance.

Pre-Sorted Sub-Kits: The 143-piece set arrives pre-organized into individually indexed, application-specific bags. This takes the guesswork out of final assembly and saves over 30% relative to sourcing individual hardware groupings separately.The master kit supplies all exterior-facing hardware needed to mount secondary components back onto a clean big-block long-block
