Overview
Speed-pro forged flat-top piston set : 383ci
Higher compression, longer life. These power forged pistons from speed-pro are designed to fit tight, thanks to a special aluminum alloy that doesn't expand as much as other alloys. They'll provide the stability and ring control you need, plus the strength you want. Speed-pro pistons also feature ribbed skirts for better oil retention, and even included new wrist pins!
