Elevate your engine's performance with a choice of compression ratios that suit your needs. Opt for stock compression when conducting a basic engine rebuild or for low boost turbo or supercharger applications. If you plan to run high-performance camshafts, added compression can significantly enhance your engine's capabilities. On the other hand, if you're aiming for a big boost turbo setup, low compression is the way to go. CP and this distributor have collaborated closely to bring you the finest pistons for your high-performance or racing engine. These pistons are meticulously crafted to meet the most rigorous standards and are unrivaled in quality. Piston Specifications: BORE: 84.5mm Rod Length: 135mm Compression Ratio: 8.8:1
