Does anyone know the bolt torque requirements for the tunnel port aluminum 4V intake manifold? I know that it is less than the standard FE intake torque of 32-35 Ft-Lbs. Thanks
The normal torque for an FE intake is 35lbs. Edelbrock recomends 25lbs. on their aftermarket intake. If you torque to 25 and run the engine and there is a vacuum leak retorque to 35. Use right stuff or RTV on the front and rear of the block to prevent seapage and to ensure a better seal.
