1966-1968 Chevelle Master Engine Bolt Kit, 283, 327, 350 with AC
1966-1968 Chevelle Master Engine Bolt Kit, 283, 327, 350 with AC, is a highly detailed, concours-correct hardware pack. Manufactured primarily by AMK Products (frequently referenced under part numbers 66-SBA or EFK347-variant configs), this set includes 164 pieces of period-accurate fasteners.
The presence of factory air conditioning dictates specific clearance hardware, unique exhaust manifold bolt configurations, and accessory-bracket accommodations that differentiate it from standard A/C-delete sets
Kit Specifications & Features
-
- Restoration Standards: All pieces are modeled after original GM factory assembly guidelines. They include correct head markings and original styles of finishes (such as phosphate-and-oil or specialized zinc plating).
- Stainless Steel Upgrades: High-visibility exterior fasteners—including the valve cover bolts, valve cover retainers, exhaust lock bridges, washers, oil pan bolts, and timing cover bolts—are made of corrosion-resistant stainless steel.
- Labeled Sub-Kits: The 164-piece bundle is pre-sorted into clearly indexed, application-specific bags. This eliminates tracking down individual fasteners and saves roughly 30% over piecing a kit together independently.
What the Kit Attaches
The comprehensive set contains the hardware needed to secure exterior peripherals back onto a clean small-block long-block:
- Induction & Fuel: Air cleaner (with phosphate wing nut), carburetor, choke cover, factory iron intake manifold, and intake plugs.
- Belts & Cooling: Crank pulley, harmonic damper, short water pump assembly, engine fan (2-3/4″ Grade-8 bolts), fan clutch, and water neck.
- Exhaust & Lubrication: Exhaust manifolds (including specialized clearance bolts for A/C setups), exhaust pipe-to-manifold studs/locknuts, oil pan, and oil filter valve.
- Ignition & Accessories: Distributor hold-down, ignition coil and mounting strap, timing cover, ignition wire brackets, PCV adapter, and flat wound spring hose clamps.
