Product Details

The Holley 300-49 Pro-Jection intake manifold is engineered specifically for Chevy small block V8 engines equipped with Holley's throttle body injection systems. This high-rise dual plane design delivers excellent power and torque across a broad RPM range from idle to 6000 RPM, making it ideal for street performance applications.

Key Features:

  • High-rise dual plane design for improved power band characteristics
  • Dedicated Holley Pro-Jection TBI mounting flange for direct bolt-on installation
  • EGR provisions for emissions compliance in street-driven vehicles
  • Optimized port dimensions: 1.89" height x 1.15" width for efficient airflow
  • Manifold height: 3.91" front, 5.40" rear
  • Power band optimized for idle through 6000 RPM operation

This intake manifold provides the foundation for a complete Holley Pro-Jection throttle body fuel injection conversion on traditional small block Chevy engines (262-400 cubic inches). The dual plane design maintains excellent low-end and midrange torque while supporting strong top-end power, making it versatile for daily driving and weekend performance.
