Pontiac Engine Rebuild Kits – Classic V8 Power & Heritage

Preserve classic Pontiac power with confidence. Our Pontiac engine rebuild kits are matched to the exact engine family and application, helping restore strong compression, smooth drivability, and long-term reliability for your GTO, Firebird, Trans Am, big-body Pontiac, and more.

Because each kit is tailored to a specific Pontiac engine, installation becomes easier and results are more consistent. In addition, quality components help protect your investment in machine work, so your engine runs better and lasts longer.

Popular Pontiac Engines We Support

Pontiac V8 engines have a loyal following, and many owners choose to rebuild rather than replace. As a result, our Pontiac engine rebuild kits cover many of the most requested classic and muscle-car platforms:

Traditional Pontiac V8 Platforms

• 326 Pontiac V8
• 350 Pontiac V8
• 389 Pontiac V8 (GTO-era)
• 400 Pontiac V8
• 421 Pontiac V8
• 428 Pontiac V8
• 455 Pontiac V8

These engines powered everything from early GTOs and LeMans models to Firebirds, Trans Ams, and full-size Pontiacs. Whether you are restoring a numbers-matching car or building a street-friendly performance combo, we can help match the correct kit to your build.

Pontiac 400 / 455 rebuild kit options

Many builders look specifically for a Pontiac 400 / 455 rebuild kit because these engines respond well to proper machining, matched pistons, and upgraded bearings. We offer packages for stock restorations as well as mild performance builds.

Street, Strip & Specialty Builds

• Street-performance Pontiac engines with upgraded cams and induction
• Bracket racing and drag-strip Pontiac V8 combinations
• Stroker Pontiac builds (application-specific)

If your specific Pontiac engine or stroker combination is not listed, let us know. In many cases, we can build or source a custom Pontiac engine rebuild kit for your exact bore, stroke, and bearing clearances.

What’s Included in Our Pontiac Engine Rebuild Kits

We offer multiple kit levels so you can choose what fits your project best. This way, you only pay for what you truly need.

• Main, rod, and cam bearings (where applicable)
• Pistons and ring sets (standard and oversizes available)
• Complete engine gasket and seal sets
• Camshaft and lifters (stock or performance, where selected)
• Timing set and related components
• Other application-specific internal parts

Whether you’re working on a factory 400 or a big-torque 455, our Pontiac 400 / 455 rebuild kit selections make it easier to match components to your machining specs.

Because each Pontiac engine rebuild kit is matched to your engine family and machining specs, there is less guesswork, fewer returns, and a smoother assembly process.

Kit Levels for Pontiac Engine Builds

Different Pontiac projects call for different kit levels. At Benning Auto Parts, we can supply:

Re-Ring / Refresh Kits

• Best for higher-mileage engines with minor wear
• Focus on rings, gaskets, and core bearings where applicable

Standard / Master Rebuild Kits

• Ideal for full rebuilds on street-driven Pontiacs
• Include pistons, rings, bearings, gaskets, and timing components

Performance & Stroker Kits

• Designed for performance street, strip, or specialty builds
• May include hypereutectic or forged pistons, performance bearings, and upgraded valvetrain components

If you are unsure which level best fits your project, our team can walk you through the options and explain what makes sense for your engine, budget, and goals.
