1955–1996 C1–C4 Chrome Timing Chain Cover Kit Small Block 3991433 - OEM Number(s) (3991433)
This chrome-plated timing chain cover kit dresses up your small block Corvette engine and installs as a direct fit, with the bolts and gaskets included for a complete job.
This chrome timing chain cover kit gives the front of your small block Corvette engine a clean, customized, show-ready look. It is a direct-fit replacement for the small block Chevrolet 265-400 (Gen I/Gen II), which in Corvette terms covers the small block cars from 1955 through 1996 — the C1 265/283/327, the C2 and C3 327/350, and the C4 350 through the L98 and Gen II LT1/LT4.
The kit includes the bolts and gaskets required for installation, so you have what you need to seal the front cover and dress up the engine in one step. It does not fit 1997-and-later Corvettes, which moved to the Gen III LS with a different front-cover design.
Fits the Following Corvette Models:
- 1955–1962 C1 Corvette — 265 / 283 / 327 small block

Features / Benefits:
- Chrome-plated timing chain cover for a customized engine look
- Direct-fit replacement for the small block Chevrolet 265-400 (Gen I/Gen II)
- Includes the bolts and gaskets required for installation
- Dresses up the front of the engine for show or street
- GM reference part number: 3991433
Material / Finish: Chrome-plated steel cover, supplied with bolts and gaskets.
Fitment Caveat — Timing Chain Clearance: For use with OEM-style timing chains only. Double-roller type chains or gear drives require checking for adequate clearance before installation.
Because Details Matter: The timing cover sits front and center on the engine, and a bright chrome piece is one of the easiest ways to lift the whole engine bay. With the bolts and gaskets included, you get the dressed-up look and a fresh front seal in a single job, the kind of detail that makes opening the hood as satisfying as driving the car.
