E-Street™ Chrysler 440
This E-Street cylinder head is ideal for entry-level street performance 1961-79 Chrysler 361-440 c.i.d. Wedge engines operating in the idle to 5,500 rpm range. The 75cc combustion chamber allows this head
to be used with stock pistons, retaining the 9.5:1 compression. The modern combustion chamber design also improves the combustion process and the larger than stock intake and exhaust ports move more air through your engine. These features improve the engine's efficiency, resulting in more horsepower and torque. 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. Additional qualities include hardened spring cups for long-term wear protection and Heli-Coil® threaded inserts in the rocker shaft bosses for increased strength; these are the details that most low-cost competitors leave out of their heads. These cylinder heads are sold in pairs.
