Wiseco produces a great 318 forged piston set for the Mopar Chrysler Plymouth Dodge 318 engine. The 318 Mopar V8, also known as the 5.2L, and 5.2 Magnum has been around since 1964 as part of the LA engine series and the 1992 and newer 318 Magnum series engines.
The 318 is a dependable, reasonably small and light, efficient engine package, that can be built to do everything from power a street work truck to being an all out drag, oval track or road racing engine. Many people tend to overlook the 318 as a high performance engine, which is a shame as it offers many benefits, and the core engines are easy to come by and relatively inexpensive.
If you do not find the pistons you need for your 318 engine on this page, we have many more 318 and 5.2 Magnum pistons available on our website. To see over 50 different sets please click here >>> 318 Piston Sets
In building up a 318, one of the main things that must be changed is the pistons. From the factory, the 318 was just about always equipped with low compression pistons, as it was intended more for long life, using low octane regular gasoline, than for high power output. Installing higher compression, higher quality pistons is one of the biggest improvements you can make to your 318 engine. When you upgrade your pistons, it is also suggested to upgrade your connecting rods.
