What engine can fit in a Buick Roadmaster 1993?

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.
