Here's why:
* Different Head Bolt Patterns: The 267 Chevy engine uses a different head bolt pattern than the 350 engine. This means the intake manifold's bolt holes won't align with the cylinder heads on a 267.
* Intake Runner Size: The 267 engine has smaller intake ports and runners than a 350. Using a 350 intake manifold would likely create mismatches in airflow and reduce engine performance.
You'll need to find an intake manifold specifically designed for a 267 Chevy engine. You can also consider using a 283 intake manifold, as they share a similar bolt pattern with the 267.
Important Note: While some "universal" or "adapter" intake manifolds exist, these are often not ideal for performance and can cause fitting issues. Always research and ensure the intake manifold you choose is specifically designed for your engine.
