A 5.7 TPI (Throttle Port Injection) intake is designed for a 5.7-liter small-block engine, typically not compatible with a 454 big block due to significant differences in engine design and mounting configurations. The intake manifold bolt patterns, port sizes, and overall dimensions differ between small-block and big-block engines. Therefore, a 5.7 TPI intake will not fit a 454 big block without extensive modifications, which are generally not practical. For a 454, a specific big-block intake designed for that engine is recommended.
