Hey Fellas,

I am trying to find information on what makes the Syclone/Typhoon piston "unique". I can't find the information that was once available explaining the detailed information. I know that they are made of a different material, but what is that? I am also seeing information regarding the engine as a Vortec 4.3, which is wrong unless I've been out of it for a couple of years.... The search here is not being my friend....

Re: Stock Engine Specifications

The pistons are hyperuethetic. The engine was marketed as a Vortec, GM freely used that term. The SBC. Vortec based heads don't appear until 1996.

"Vortec is a trademarked name for a line of piston engines for General Motors trucks. The name first appeared in 1988 on a 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air/fuel mix. Now it is used on a wide range of different engines. Modern Vortec engines are named for their approximate displacement in cubic centimeters."

In 1996 the heads were redesigned and are referred to as "Vortec heads", these are the ones that everyone typically wants.... our trucks by GM definition have a Vortec engine including Vortec heads, despite the heads not being the highly desirable 1996 and later versions.

The original SyTy pistons have a higher Silicon content than regular pistons.

Quote from Wiki page: "Hypereutectic pistons are stronger than more common cast aluminum pistons and used in many high performance applications. They are not as strong as forged pistons, but are much lower cost due to being cast."
