EC Carburetors EC Wildcat 223GT1 4-Cycle Racing Engine W/ 10w-30 Maxima Pro Plus Oil

The New Wildcat 223GT1 is a modified version of the Wildcat 223 Engine.

The Wildcat 223 is one of the best stock engines on the market, with one of the strongest blocks in the industry and the largest displacement of any factory engine. The New Wildcat 223GT1 is a stage one Wildcat 223 engine with upgrades to make them race-ready. 

The Wildcat can easily increase its compression due to its larger displacement and reduce compressed or squish volume thanks to EC’s 3.353-Inch Pinnacle forged connecting rod that puts the flat top piston at zero deck. Next, the stock coil and cast iron flywheel are removed and replaced with a cast aluminum flywheel for reduced weight and higher rpm safety. 22lbs springs are added to raise the valve float limit to 6500rpms. The stock carburetor is re-tuned and jetted on the dyno for optimal performance. 

These engines are ideal for those in super stock, mod stock, and other mildly modified or claimer classes. Check with your rules for eligibility.
