Dart and Chevy SHP Block Oil Restrictors

Optimize the oiling system of your Dart or Chevy SHP engine block with Allstar Performance Oil Restrictors. Featuring a precise .090-inch hole, these restrictors are designed to provide the exact flow rate needed for high-performance Small Block Chevy applications. By controlling the oil volume delivered to the top end, these restrictors help maintain stable oil pressure in the bottom end, which is vital for preventing bearing failure under extreme racing conditions.

Key Technical Features

  • Engine Fitment: Designed for Dart and Chevy SHP Small Block engine blocks.
  • Precision Flow: .090-inch orifice for accurate oil volume management.
  • Construction: Lightweight aluminum with a natural finish.
  • Installation: Allen head design for a secure, flush-fit installation.

In high-RPM engines, excessive oil in the valvetrain can lead to increased oil temperature and aeration, both of which are detrimental to performance. These restrictors allow you to dial in your oiling system, ensuring that your engine maintains optimal pressure throughout the entire power band. The use of high-quality aluminum ensures that these restrictors are both lightweight and durable enough for the rigors of competitive racing.

Whether you are building a drag racing engine or a high-end street motor, these restrictors offer the reliability and performance you expect from Allstar Performance. They are easy to install and provide a significant improvement in oil system efficiency. Trust the experts at GGCRACING to provide the high-performance engine parts you need to keep your vehicle running at its peak potential. Shop our extensive catalog today.
