Description

EC 223cc Stroker Rotating Assembly – Fits Ducar / Tillotson 212E Hemi Blocks


Increase displacement and boost performance with this precision-engineered rotating assembly, designed specifically for the taller-deck Ducar and Tillotson 212E blocks.


This complete stroker kit raises engine displacement to 223cc while solving the typical fitment challenges associated with stroker builds—including rod length, crank clearance, and piston height.


Unlike Predator-based stroker kits, the EC 223cc kit is built around the unique deck height of the Ducar and Tillotson 212E Hemi blocks, delivering a true drop-in upgrade for racers looking to gain displacement in classes that allow Ducar or Tillotson engines.


What’s Included in the Kit:

Wildcat 223cc 70mm Flat Top Piston

  • Engineered for increased skirt-to-counterweight clearance
  • Complete assembly: rings, wrist pin, and circlips included
  • Lightweight design reduces rotating mass for quicker revs

8270 EC Pinnacle Forged Connecting Rod

  • Custom-forged to match the deck height of the 212E block
  • Sets piston at or near zero deck height (minor variance may occur due to block casting)
  • Dipper design avoids interference with camshaft, easing installation

Wildcat 58mm Stroker Crankshaft

  • Same crank used in the EC 236R and Wildcat 223 engines
  • Compatible with Honda/Clone-style tapered flywheels (not Hemi-style)
  • May require clearance for the cam’s compression release depending on cam profile
  • Recommended flywheels: SK200 or SK201 Rev Wheel


Key Features & Benefits:

  • Increases engine displacement to 223cc
  • Designed specifically for Ducar and Tillotson 212E Hemi blocks
  • Eliminates common stroker build clearance issues
  • Ideal for racing classes that allow Ducar or Tillotson engines
  • CNC-matched piston and rod combo ensures precise deck height control
  • Great alternative to full engine replacement for racers on existing 212E platforms


Important Compatibility Notes:

  • Not compatible with Tillotson 212R engines
  • Hemi flywheels will NOT fit the included crankshaft
  • Engines using 58mm crankshafts (Wildcat 223, Predator 224, etc.) may require cam clearance machining for the compression release
  • For more valve clearance, consider using the 223H-SKA rod kit, which will position the piston approximately .020” in the hole


Installation Recommendations:

  • Piston will be approximately zero to .010” popup – use a .045” or thicker head gasket
  • Always check piston-to-valve clearance, especially when using the stock Hemi head
  • For those wanting a complete, ready-to-run 223cc engine, the Wildcat 223 offers better components and overall value compared to stroking a 212E block


Summary:

This EC 223cc rotating assembly is the go-to solution for racers seeking extra displacement from their Ducar or Tillotson 212E engines without the full cost of a new engine. Purpose-built to address deck height differences and internal clearancing, this kit simplifies your build while unlocking real performance gains.

FAQ

Q1: What engines is this stroker kit compatible with?

A: This kit is designed specifically for Ducar 212E and Tillotson 212E Hemi engines. It is not compatible with the Tillotson 212R or other engines without modification.


Q2: Why does this kit need a different rod than the Predator 212 stroker kits?

A: The Ducar and Tillotson 212E blocks have a taller deck height than Predator 212 engines. This requires a slightly longer rod to bring the piston flush with the deck at top dead center.


Q3: Will this kit fit the Predator 224 or Wildcat 223 engine?

A: No, while they share a similar crank size, this kit is specifically configured for the deck height and block geometry of the 212E Ducar/Tillotson engines.


Q4: What kind of head gasket should I use with this kit?

A: Because the piston may sit zero to .010" above deck, we recommend using a .045” or thicker head gasket to ensure proper quench and avoid contact with the head.


Q5: Will I need to clearance anything to make this kit work?

A: Possibly. Some engines may require clearance around the camshaft’s compression release to avoid interference with the 58mm crankshaft. This depends on your cam’s profile and cam core.


Q6: Can I just buy a complete 223cc engine instead?

A: Absolutely. If you're looking for the best value and stronger components, we recommend the Wildcat 223cc Engine, which costs less than building a 223 from a 212E and includes higher-quality internals.
