* Motor mounts: The 350's mounting points won't align with the Firebird's existing mounts. You'll need aftermarket motor mounts designed for this swap.
* Transmission: The transmission must be compatible with both the 350 and the Firebird's drivetrain. This might require an adapter plate or a different transmission entirely.
* Exhaust: The exhaust system will need to be custom-fabricated or significantly modified to fit the larger engine.
* Wiring: The wiring harness for the 350 will likely be different and will need to be adapted or replaced.
* Steering: In some cases, the steering shaft may interfere with the engine or accessories.
* Hood clearance: Depending on the intake manifold and other accessories, you may need to modify or replace the hood to provide sufficient clearance.
In short, while it's possible, it's a significant undertaking requiring mechanical skills, specialized tools, and potentially a good bit of fabrication. It's not a simple swap like changing a lightbulb. Many people opt to use a kit to help simplify the process, making the install easier but still requiring mechanical knowledge and expertise.
