Yes, a 1969 455 Buick engine can fit into a 1985 Buick Regal, as both vehicles share a similar body platform. However, some modifications may be necessary, including adjustments to the engine mounts, transmission compatibility, and possibly the exhaust system. Additionally, the 455 engine is larger and heavier, so it's important to ensure that the suspension and brakes can handle the increased power and weight.
