The HEMI engine powered cars are the most powerful ones that you are going to find on the market. Whether it is a  big block HEMI or the small block HEMI, they are all working perfectly. And they are all going to power those wheels on the Plymouth Cuda, but how exactly does the HEMI engine work and why it is better than the VR6 coming from Volkswagen or the Cummins that can be found in the Dodge vehicles? These questions are going to be considered and answered by the host as he is eager to teach us more about the legendary HEMI engine.

Before the modern build of the HEMI there was the “flat head” design on the pistons. These are the older generations of the HEMI and they are still used today, but as we know over the years they have been improved as well. The problem about the flat head design was that there was small amount of volume in the engine for the pistons and a large surface area on the piston head. The HEMI engine got its name from the hemispherical shape of the head so in short it is a HEMI. So what does it do with this shape?

The HEMI is MAXIMIZING the volume and it minimizes the surface area of the head of the piston, so it makes it a lot better than the older engines of this family. Wasting heat was the problem and with the area gotten smaller this problem has been solved easily. So the legendary HEMI engine got a lot better with the hemispherical shape and it became the most used engine back from 1990s to 2000.

It is still famous among the Mopar and the HEMI followers too and we have seen a lot of swaps with the HEMI engine fitted in some Fords or even BMWs too.
