What is the compression ratio achieved with these pistons?

These Mahle pistons feature a -1.6cc dish volume, which results in a 9.7:1 compression ratio when used with a compatible 310 cubic inch Small Block Chevrolet engine build. This ratio is generally suitable for pump gas applications.

What material are these pistons made from?

The pistons are forged from 4032 aluminum alloy. This material is chosen for its good balance of strength, durability, and thermal expansion characteristics, making it well-suited for performance engine builds.

Are these pistons compatible with all SBC engines?

This specific piston set is designed for 310 cubic inch Small Block Chevrolet engines with a 3.766-inch bore. While it fits the general SBC architecture, precise fitment depends on the specific engine displacement and bore size.
