Will a lt1 fit in Cadillac Fleetwood?

Yes, an LT1 engine can fit in a Cadillac Fleetwood, particularly if the Fleetwood is from the late 80s to early 90s, as these models often share a platform with Chevy full-size cars. However, modifications may be necessary for proper fitment, including adjustments to the engine mounts, transmission, and exhaust system. It's also important to consider the vehicle's electrical and cooling systems to ensure compatibility with the LT1.
