300-275 Carbureted Hi-Ram Intake Manifold Base
Features:
- 3/32 in. round O-ring cord plenum top gasket
- 2.000 x 1.190 in. Port Size
Notes:
- Requires a low profile distributor
- Many Ford vehicle models were originally equipped with a heater core flow restrictor located at either the original heater hose fitting in the factory intake or inline in the inlet heater hose which protects the heater core from damage. If you are replacing the hoses between the engine and heater core or changing the factory fitting check to see if your application requires a flow restrictor. Failure to use the proper flow restrictor will likely result in a damaged or leaking heater core.
Emissions Note:
This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.
