Yes, a 455 engine can fit in a Buick Roadmaster, particularly if it is from the same era (the late 1960s to early 1990s) when both the engine and vehicle were produced. However, some modifications may be necessary, including adjustments to the engine mounts and possibly the transmission. It's important to ensure compatibility with the vehicle's existing systems, such as cooling and exhaust. Always consult with a professional mechanic or restoration expert for specific advice related to your project.

The 1993 Buick Roadmaster typically comes equipped with a 5.7-liter LT1 V8 engine, which is a popular choice for this model. However, other engines that can fit include the 5.0-liter and 5.7-liter small-block Chevy V8s, given their compatibility with the vehicle's drivetrain. It's important to ensure any engine swap is matched with the appropriate transmission and that modifications comply with local regulations.
Pontiac 455 headers generally do not fit a Buick 455 due to differences in the engine's exhaust port locations and bolt patterns. While both engines are part of the General Motors family and share some similarities, the specific design and dimensions of the exhaust manifolds and headers vary. If you're looking to upgrade to headers for a Buick 455, it's best to choose headers specifically designed for that engine to ensure proper fit and performance.
