The Vortec designation was used for a series of fuel-injected small-block and big-block V8 engines produced by Chevrolet from the early 1990s to the late 2000s. While the 454 was a big-block engine, it was typically carbureted and did not receive the Vortec treatment.
Here's a breakdown:
* 454: A big-block engine with a 7.4L displacement (454 cubic inches).
* Vortec: A series of engines featuring fuel injection, improved cylinder heads, and other design changes for increased power and efficiency.
Note: While Chevrolet did not produce a factory-built 454 Vortec, some aftermarket companies may offer modified 454 engines with Vortec-style components. However, these are not official Chevrolet products.
