Edelbrock E-Street Cylinder Heads for Big-Block Chevy...
Edelbrock has expanded their line of E-Street cylinder heads to include an application for oval port big-block Chevy’s. This new 290cc head is designed for entry-level street performance and offers high quality at an affordable price.
Manufactured in the USA, these heads are made from A356 aluminum castings that are heat treated to T-6 specifications for superior strength and quality. Features include larger than stock (290cc) intake and (110cc) exhaust ports for improved engine efficiency; resulting in more horsepower, torque and increased mileage potential. Hardened spring cups help protect long-term wear along with the Heli-Coil threaded inserts for exhaust flanges and rocker studs; these are the items that the lower-cost competitors leave out of their heads. These new heads are equipped with 7/16-inch rocker studs and double valve springs to handle valve lifts up to .700-inch. The combustion chambers measure 110cc and their 2.19-inch intake valve and 1.88-inch exhaust valve combo produces great horsepower and torque. These E-Street heads are assembled with manganese bronze valve guides and stainless steel valves with hardened tips. Applications are available bare (PN 50449) and complete with valvetrain (PN 50459.
