Stroker Rotating Assembly

The EC Carburetors 223H-SKA stroker rotating assembly is purpose-built to increase the displacement of the Harbor Freight Predator 212 Hemi engine to 223cc, yielding more torque and horsepower. The kit includes a Wildcat 223cc 70mm flat-top piston designed for clearance between crank counterweights and the piston skirt, featuring lightweight construction for faster revs and reduced rotating mass. The EC Pinnacle 3.271” forged rod is precision-forged for durability and is 0.030” shorter than stock to achieve a zero-deck height with the included piston. Its dipper design also eliminates camshaft interference, simplifying installation. The Wildcat 58mm stroker crankshaft is the same unit used in EC's 236R and Wildcat 223 engines, designed for maximum stroke in Predator Hemi blocks. This rotating assembly is ideal for builders competing in Predator-only race classes where maximizing performance within specific engine branding is crucial. The kit is compatible with Honda/Clone tapered flywheels; Hemi flywheels will not work. EC recommends pairing it with their SK200 or SK201 Rev Wheels for optimal results. Important compatibility notes: This kit is specifically designed for the Harbor Freight Predator 212 Hemi and is not recommended for Predator Non-Hemi or other 212/223 clone variants like Wildcat or Ducar blocks due to differing deck heights. Installation may require minor clearance machining, particularly around the camshaft's compression release area, to accommodate the 58mm crankshaft. Using a cam with a 224 core can simplify this process. The stock Hemi side cover works without issues.
