3.4 Twin Dual Cam

The 3.4 Dual Twin Cam V-6 engine, a marvel of engineering, is a powerhouse that boasts high-performance capabilities and a high-revving nature. Its design, a sleek 60-degree configuration, makes it a perfect replacement for the factory-installed engine in a Fiero.

One of its standout features is its weight-saving aluminum heads, a testament to modern engineering efficiency. These heads not only reduce the overall weight of the engine but also enhance its performance. The engine’s compatibility is another of its strong suits. It can seamlessly bolt directly to both 4-speed and 5-speed transmissions, offering flexibility in terms of integration.

This engine isn’t just a standalone marvel; it has a rich history of being the heart of several cars. It was the stock engine in a range of vehicles including the 1991-1994 Chevrolet Lumina Z34, the 1991-1995 Oldsmobile Cutlass Supreme, and the 1991-1996 Pontiac Grand Prix. This pedigree speaks volumes about its reliability and performance.

Our personal journey with this engine began in the late 1990s. It was the first engine swap we undertook in our personal build, marking the start of an era of innovation and transformation. This build stands out as one of the most notable projects that WCF has undertaken to date.

Over the years, WCF has built numerous parts to support this engine swap. Each part has been meticulously prototyped and rigorously tested in our very own car, ensuring the highest standards of quality and performance. This commitment to excellence underscores our dedication to providing the best for our vehicles.

In essence, the 3.4 Dual Twin Cam V-6 engine is more than just an engine; it’s a testament to the possibilities of automotive engineering and our commitment to pushing the boundaries of what’s possible.
