What is the compression ratio with these pistons?

These Mahle MS pistons feature a -6cc dish volume. When used with a 5.4-inch connecting rod and a 0.927-inch wrist pin in a 348 cubic inch Ford Small Block engine, they achieve a 10.1:1 compression ratio.

What material are these pistons made from?

The pistons are forged from 4032 aluminum alloy. This material is chosen for its strength and ability to withstand high temperatures and pressures commonly found in performance engine builds.

Are these pistons balanced?

Each piston in this set weighs 404 grams. While Mahle manufactures them to consistent weight specifications, it is always recommended to have the entire rotating assembly professionally balanced after installation for optimal engine performance and longevity.
