Will a 97 Chrysler Lhs engine fit in 99 body correctly you would like to no its the 3.5liter?

No, a 1997 Chrysler LHS 3.5L engine will likely not fit directly into a 1999 Chrysler LHS body without significant modifications. While both are 3.5L engines, there were changes made to the engine bay and possibly the engine itself between the 1997 and 1999 model years. These changes could include:

* Engine mounts: The location and design of the engine mounts may differ.

* Wiring harness: The wiring harness connectors and routing may be incompatible.

* Exhaust system: The exhaust manifolds and routing could be different.

* Accessory components: The placement and connections of components like the alternator, power steering pump, and air conditioning compressor might be different.

Even if the block itself seems similar, the surrounding components and their integration into the chassis are crucial for a proper fit. Attempting this swap would likely require extensive fabrication and custom work. It's a complex undertaking and not generally recommended for a novice mechanic.
