Upgrade or replace your Chevy Big Block Mark IV timing cover with this complete 1-piece polished aluminum cover kit, designed for fitment-focused engine builds, rebuilds, and leak repair. It helps seal the timing chain area while giving the front of the engine a clean, finished appearance.

Unlike TSP's cover-only version, this kit includes everything needed for installation: crankshaft seal, timing cover gasket, water pump gasket set, and a bolt & washer set. This is a plain-design, long-water-pump application cover — verify your engine uses a long (not short) water pump configuration before ordering, along with balancer clearance and sensor provisions.

Applications
Fits Chevrolet Big Block V8 Gen II (Mark IV): 6.5L/396, 6.6L/402, 7.0L/427, 7.4L/454 in³, long water pump configuration only. Common on Chevelle, Camaro, Nova, C10/C-K trucks, Corvette, Impala, and Caprice big block applications, as well as street, strip, and rebuild builds.

Installation
Verify your engine uses a long water pump before ordering — this cover is not designed for short water pump configurations. Also confirm balancer clearance and sensor provisions before installation.
