    I am going to rebuild my 350 and would like some information on the best pistons for my blazer. What is the different between cast, forged, and Hypereutectic? The Blazer ill be a all around truck used for off-road and street use.

    cast = cheap
    hyperuetectic = expensive cast piston
    forged = good piston but may have more oil consuption issues when cold depending on who built it and for what application

    Cast Pistons- are what the engine usually comes with stock. They are ok for a stock engine or mild performance add ons.

    Hypereutectic.- Also used in some OE engines. They are better than cast. They wear better and give more power, reduced emissions ect. They are made up of a aluinimium alloys that contain silicon.

    Forged Pistons are usually used in high performance applications. They are kind of expensive for use a daly driver that you are not going to put heavy loads on.

    As for Pistons I like Silvolite Pistons they have always worked well for me.

    Basically with pistions... you get what you pay for if you are going high performance. I like JE's the best. But for cheaper builds the new speed pro are ok among others. I'm not reall a big Keith Black fan.... but the Silver-lites are a good piston for a mild motor

    pushing a heavy truck with a small motor is heavy loads
