NEW from Edelbrock - E-Street™ for S/B Chevy
E-Street™ cylinder heads are an all new line of Edelbrock heads designed for entry-level street performance engines, ideal for operating in the idle to 5,500 rpm range. Manufactured in the USA, by Edelbrock, these heads feature A356 aluminum castings that are heat treated to T-6 spec for superior casting strength and quality. Their modern combustion chamber designs improve the combustion process and larger than stock intake and exhaust ports move more air through your engine. These features improve an engine's efficiency, resulting in more horsepower and torque and improved mileage potential. Dyno tests showed a gain of 16 hp and 11 ft/lbs of torque over our overseas competitor.
