What is the compression ratio achieved with these pistons?

These pistons feature a -28cc dish volume. When paired with the appropriate crankshaft and cylinder heads for a 416 cubic inch Small Block Mopar engine, this configuration results in a 9.4:1 compression ratio.

What material are these pistons made from?

The pistons are constructed from 2618 aluminum. This material is chosen for its strength and ability to withstand the high temperatures and pressures found in performance engine applications.

Are these pistons suitable for use with standard pump gasoline?

With a 9.4:1 compression ratio, these pistons are generally suitable for use with standard pump gasoline in many performance street applications. However, proper engine tuning and consideration of other engine components are always recommended for optimal performance and reliability.

Product Details

Mahle is a well-known name in engine components, particularly for their piston technology. This MS Piston Set is built for Small Block Mopar (LA) engines, specifically for builds aiming for a 416 cubic inch displacement. If you're putting together a performance engine or rebuilding a classic Mopar, these pistons are designed to handle the demands of a higher-performance application.

This set features a 4.070-inch bore and is designed to work with a 4.000-inch stroke crankshaft and a 6.123-inch connecting rod. The pistons have a -28cc dish volume, which, combined with other engine components, results in a 9.4:1 compression ratio. This compression ratio is a solid choice for many performance street applications, offering a good balance of power and pump gas compatibility. Each piston weighs in at 505 grams, which is a notable weight for a forged piston of this size, contributing to good rotational balance.

These pistons are constructed from 2618 aluminum, a material known for its strength and durability under high temperatures and pressures, making them a strong option for performance builds. The set includes eight pistons, along with the necessary pins (.984 inch diameter). Please note that this piston set is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
