Mopar Forged Pistons Dodge Chrysler Plymouth 340 360 383 400 440 Ross
Racing Pistons
ROSS Racing Pistons are used in high performance and racing engines by knowledgeable
engine builders the world over. Here you will find Ross Racing Pistons for use
with the following Mopar engines, 340, 360, 400, 440, 392 Hemi and many different stroker
pistons. They combine light weight, high strength, precision machining and premium
materials to build a piston you can depend on for high horsepower, torque and reliability.
We offer these superb pistons at very affordable prices.
Ross Racing Pistons offers pistons in both stocking and custom sets. In most cases you
can find a stocking set to fit your needs. If you do not see the exact piston specs you
want in a stocking piston, we will be happy to help you with a custom piston design. Custom
pistons can be made for just about any type of engine. Please contact us and we will be happy to assist
you with a custom piston order.
ROSS includes forced pin oilers and double spirolox on all of their stocking pistons.
Pistons are balanced to plus or minus 2.5 grams throughout the set. You can buy
replacement pistons one at a time as needed. The valve pockets are designed to handle most
camshaft applications. The skirt design allows the pistons to work properly under intense
heat and tremendous side loads without scuffing or splitting cylinder walls. Most normally
aspirated pistons are designed to operate at .004 piston skirt to cylinder wall clearance.
All ROSS stocking pistons include aircraft quality pins that are heat treated and end
ground to work in full floated or press fit applications.
Please feel free to use our compression ratio calculator to calculate the compression ratio of these pistons with different cylinder head chamber volumes.
