* Motor Mounts: The engine mounts may need to be changed or modified to fit the RS's frame. The IROC-Z might have different mounts due to any performance upgrades.
* Wiring Harness: The wiring harness from the IROC-Z 350 might not be directly compatible with the RS's electrical system. You'll likely need to adapt or replace parts.
* Exhaust System: The exhaust system will almost certainly need to be modified or replaced to fit the new engine.
* Transmission: The transmission used in the IROC-Z 350 will need to be compatible with the RS. This might require an adapter plate or other modifications depending on the specific transmission.
* Cooling System: Potential adjustments to the radiator and coolant hoses might be necessary.
In short, while the physical space exists, it's not a simple swap. It'll require mechanical skills, fabrication abilities, and likely some custom parts to get everything to work correctly. Expect to spend considerable time and money on the project.
