One of the most popular items in our line up of 360 performance parts are replacement pistons and rings. High performance KB Chrysler Plymouth Dodge 360 pistons offer a significant performance improvement for your engine, at a very affordable price. We have these piston sets available in a wide range of sizes including standard bore and many popular oversizes. Also included are 360 stroker pistons that are used with a 4 inch stroker crank to build a 360 into a 408 cubic inch engine.
If you are rebuilding a Chrysler, Plymouth, Mopar, Dodge 360 small block engine and are looking for improved performance, without the higher cost of forged pistons, KB performance pistons are an excellent alternative for many street, muscle car restoration, cruising and street / strip applications.
We do not recommend hypereutectic pistons for use with superchargers, turbochargers, nitrous systems or for serious racing engines. For those applications we strongly recommend forged pistons. Our complete piston index list for stock replacement, cast, hypereutectic and forged pistons is available here: CE Engine Pistons Index

While you are replacing your engine pistons it is a good time to also upgrade your rotating assembly by installing modern connecting rods. Why risk damage to your rebuilt performance engine by using old stock connecting rods that have been through who knows what kind of abuse.
With the high cost of machine shop service these days you can often upgrade to far stronger modern rods for not much more than the cost of reconditioning a set of stock rods.
