Description
If you’re building a high-compression Small Block Chevy engine, combustion chamber geometry directly impacts power output and detonation resistance. This forged piston set delivers the compression ratio you need with a proven 23-degree dome design that optimizes flame travel and cylinder pressure. The +8cc displacement increase makes these pistons ideal for stroker builds or any application demanding reliable, repeatable performance at elevated boost levels.
