For those who want more horsepower, Mopar Performance Parts offers an even hotter Magnum
380. The Magnum family of engines is at a higher level of development than any of our past
engines, even without modifications. This allows larger horsepower gains to be achieved with
similar changes. The Magnum 380 crate motor head is a swirl port design that has smaller
combustion chambers and a higher compression ratio (nominal 9.0:1). Different intake and
exhaust port sizing flows more air without modifications to the cylinder heads. Breathing is
enhanced with 1.925" intake valves and 1.625" exhaust valves.
Overall package of smaller valves and better ports flow more air. Next, we slide in our .501" / .513"
lift, 288/292 degree duration hydraulic roller camshaft, add a 4BBL carbureted M1® single plane
intake manifold (with bosses over each runner for future MPI). We add special valve springs and
a double roller timing chain as well as an MPP electronic distributor.
The distinctive Mopar cast valve covers with 10 screws are added to the package, with an oil pan
(center sump) similar to the Commando engines. It is recommended you add your own 750 cfm
Holley carburetor and headers to complete the package.
Dyno testing with a 750 cfm carburetor and 17/8" headers show horsepower output to be 380+
at 5300 RPM. Torque output is 410+ lb/ft at 4400 RPM, with over 350 lb/ft available from 2000
to 5700 RPM.
Install a completely new (not rebuilt) Magnum engine assembly and have more power than even
the “Muscle Car Era” small blocks had!
