Eagle Pontiac 400/455 Press Fit H-Beam Connecting Rod (Set of 8)

What you get in this package is a set of eight Eagle H-Beam connecting rods, specifically designed for Pontiac 400 and 455 cubic inch engines. These rods are built for serious performance, recommended for competition use where strength and reliability are critical. They feature a press-fit design, meaning they'll require a proper press for installation onto the crankshaft, and are sold as a weight-matched set to ensure balanced rotating assembly performance.

These connecting rods are forged from 4340 steel, a well-known material for its strength and durability under high stress. They start as a two-piece forging and then undergo a fully machined process, followed by shot peening. This shot-peening process helps to relieve internal stresses in the metal, making the rods even more resistant to fatigue and cracking, which is crucial for engines pushed hard. Eagle holds the sizing to exact tolerances, ensuring a precise fit and consistent performance across all eight rods in the set. This attention to detail is what you'd expect for a competition-level component.

This set fits a wide range of classic Pontiac vehicles, including models like the Firebird, GTO, and Grand Prix from the late 1960s through the late 1970s. Because these are competition-grade parts, it's important to ensure your entire rotating assembly is up to the task. If you're rebuilding a high-performance Pontiac engine for racing or serious street use, these rods are a solid choice for handling the increased demands.
