Ford V8 302 351 Cleveland Thermostat Restrictor Plate Bronze Bypass

Bronze bypass plate from Aeroflow designed to fit Ford Cleveland 351 engine blocks. This bypass plate is pressed into the block directly under the thermostat, required for correct thermostat operation and help make the cooling system effective.

Machined from solid brass for precision and longevity, it features an inside diameter of.750", equal to the original restrictor found in all Ford Cleveland blocks.

• Directs flow to the radiator by partially closing the orifice when the thermostat opens, preventing coolant from recirculating within the block.
• Designed specifically for Ford Cleveland 351 engine blocks, ensuring a precise, OEM-like fit.
• A thermostat is required to operate the restrictor plate correctly and achieve intended cooling performance.

Install by pressing the plate into the block directly under the thermostat to ensure proper function within the factory cooling system.
