Engine Builder Magazine’s 2014 Charity Engine Build

Chrysler 392 Magnum V8 engine. Produces 477 hp at 5800 rpm and 481 lb. feet of torque.

Engine Specs: 6.4L, 392 cubic in., 4” stroke crank Muscle Engine

Project Builders: Special thanks to Stacey Redmond and Joe Degraw, owners of Grawmondbecks Competition Engines, Mason City, IA, who dedicated their time and expertise, turning this donated 1977 318 Chrysler engine into a 392 Magnum.

Proceeds: This finished engine is being auctioned off for charity and the money raised will be donated to the Independence Fund, which assists disabled veterans with motorized wheelchairs.


Applications/Compatibility: This unique, muscle car motor is the perfect powerplant for any live rear-axle driven Chrysler, Plymouth or Dodge muscle car, custom ride, classic/antique car or pickup truck.

Project details: Cam specs look strong for a 340-360 cubic inch motor, but should be quite streetable with 392 cubic inches. The advertised duration is 276/284 (int/exh), with 234/242 at .050’ lift. The cam has a lobe separation angle of 110 degrees, with a 106 intake lobe centerline. Our Magnum heads use a stud-mounted rocker with a 1.6 ratio. The book specs on our cam state .513/.533” lift (int/exh), providing the motor a higher theoretical lift of .547/.569” lift (int/exh).


The team increased the size of the intake valves from 1.920” to an even 2.00”, while the already substantial exhausts went up slightly from 1.625” to 1.650”.
