Muscle Motors proudly introduces it’s biggest and badest pump gas engine EVER! The King Krate is the latest engine in our very popular series of “Killer Krates”. With 622” of ground pounding, axle shredding power, you are sure to become very good friends with your local tire man.

We start with Mopar Performance’s new performance engine block made by World Products. The King Krate has a 4.560 bore and a 4.750 stroke. Dished Ross pistons w/ Akerly & Childs rings keep the cylinders sealed to produce more torque that you can imagine. A 7.100 long H-beam rod with ARP 2000 rod bolts connect the cylinder pressure to the crankshaft. An aluminum oil pan with a single line external Muscle Motors oil system keep everything well lubricated.

We use B1 heads for the King Krate a number of reasons. The big ports will usually kill bottom end torque but with a 4.75 stroke and 622” the heads are a perfect for the King Krate. We fill the heads with stainless steel valves, 10 degree locks & retainers, roller cam valve springs and roller rocker. The heads are bowl ported and flow over 400 cfm. The cam is a proprietary grind done for us by Comp Cams and is under .700 lift for durability. A large single 4bbl intake and sheet metal valve covers finish off the heads.

And now the nitty gritty: 915 HP @ ONLY 6000  and 882 ft/lbs @ 4500! Think about this: The KING makes over 700 HP @ 4200, 800 HP @ 4800 and 900+HP @ 5700! it makes over 800 ft/lbs from 3000-6000 RPM’s!!!! Talk about torque monster, The KING also make OVER 800 ft/lbs from 3000-6000 RPM’s!!!!! Got Torque? We do!!! See the reverse side for dyno information.
