Are 5.7 and 6.1 HEMI heads the same?

A better bet is to use the 6.1L head on the 5.7. You’ll need to use the thicker head gasket, the D-port headers, and the 6.1L intake (or can you use the Eagle intake). The heads will flow like the Eagle ports and you get the improved valvetrain as well.

Are HEMI heads better?

HEMI Advantages With a flat head, the amount of surface area relative to volume of the combustion chamber is large. In a HEMI engine, the surface area is much smaller than in a flat head, so less heat escapes and peak pressure can be higher.

Are Gen 3 HEMI heads interchangeable?

The main difference is the way the center exhaust port flanges are drilled for the exhaust. OE heads are only drilled with two bolt holes per exhaust port. This Edelbrock Gen III Hemi head is drilled with four bolt holes for each port to allow the heads to be interchangeable.

Are 5.7 HEMI heads aluminum?

When the 2009 VCT 5.7L HEMI V8 engine was being updated and revised, a great deal of attention went into the cylinder heads. Like its previous versions, these heads are cast aluminum and feature a twin-plug design for better efficiency. The major change on the new heads came in the intake and Exhaust ports.

Is the 5.7 HEMI a cast iron block?

The production 5.7L crankshaft is made from cast iron and can be reused in many applications. However, if you’re bolting on a supercharger or turbocharger, you’ll need to go with an aftermarket forged rotating assembly that not only includes the crankshaft, but also connecting rods and pistons.

What makes a HEMI engine more powerful?

A HEMI® engine is composed of a hemispherical combustion chamber with dome shaped cylinders and matching piston tops. This creates less surface area than traditional engine which means that less heat and energy lost, and more power is produced.

What is the difference between a 5.7 Hemi and a 6.4 Hemi?

The 6.4 HEMI generally offers an extra 75-100 horsepower over the 5.7 engine. Thanks to larger displacement the 392 is also good for an extra 60-80 lb-ft. Low-end torque is also about 70 lb-ft more than the 5.7 further widening the gap between the two.
