Description
If you’re rebuilding your 2.3L Ford engine or pushing it toward higher compression ratios, a quality piston set is non-negotiable. Wiseco’s forged flat-top design delivers the strength you need for reliable street and track duty while optimizing combustion efficiency. This is a core component that directly impacts power output and engine longevity—get it right from the start.
The flat-top geometry reduces combustion chamber volume by 3.4 cc, raising compression for better ignition and throttle response. Forged construction resists the extreme pressures of high-RPM operation, whether you’re tuning for naturally aspirated performance or planning future forced induction. These pistons are engineered to the tolerances your engine demands.
