Official Release:

Edelbrock Adds Big-Block Chrysler Cylinder Heads to its Popular E-Street Line

Adding to their line of E-Street cylinder heads, Edelbrock has announced the addition of the Big-Block Chrysler for 361-440 cid B and RB applications. E-Street cylinder heads are an affordable line of aluminum performance cylinder heads designed for street performance engines operating in the idle to 5,500 rpm range.

Manufactured in the USA, these heads feature the quality details of higher priced cylinder heads at an affordable price. They are cast from A356 aluminum and heat treated to T-6 spec for superior casting strength and quality. Their combustion chamber designs improve the combustion process and larger than stock intake and exhaust ports move more air through an engine to improve efficiency and produce more horsepower and torque. Every E-Street head is assembled with manganese bronze valve guides, powder metal valve seats and stainless steel one-piece valves with hardened tips. As added value, E-Street heads include hardened valve spring cups to prevent premature casting wear and Heli-coil threaded inserts in the rocker stud bosses to ensure proper torque load without stripping the threads; these are the quality details that most low-cost competitors leave out of their heads.

Big block Chrysler E-Street heads feature 210cc intake ports and 84cc combustion chambers and are equipped with valve springs to handle up to .600″ of valve lift. The OE style valve train accepts factory shaft mount rockers. All E-Street cylinder heads are made in the USA.
