Yep............most modern engines, utilse this "poly" head design.
Not a "true" Hemi at all????
DirtyDog has hit the nail on the head. Our trucks would have a LOT more get up and go, if only Chrysler had got the transmission right!
100hp transmission losses, just don't cut it.
Al.

 

**** it, i drive a HEMI.

 

That's do borderline taunting someone else on this site... so I don't know if I will take this bait or not... though I know it would be a week before he would even be on to have a chance to see it... I dont know...

Hammer said I had to be nice...

Chrysler came up with the "HEMI" name so if Chrylser calls the modern engine a Hemi then its a "Hemi". It would be different if Ford bought the name and used it as a marketing tool.
If Chrysler says its a Hemi then its a Hemi.

 

Hemispherical - a. A half of a sphere bounded by a great circle.
b. A half of a symmetrical, approximately spherical object as divided by a plane of symmetry.

Poly - As a prefix, means more than one many.

Spherical - Duh.

So, poly spherical means there is more than one section of a sphere in the head, but still, I think you could consider it a Hemi because it is hemispherical, but just multiple times.

 

There are a lot more engines than you think that have the hemispherical cylinder head and was actually very common on early engines (usually foreign) even before Chrysler thought of the HEMI.

IMO the HEMI name is just a sales tactic.

 

Chrysler's first Hemi was on the V-16 aircraft engine that was supercharged, turbocharged, and intercooled. It made 2500HP and WWII ended before it went into production.

What foreign company made one before the early 1940's?

Edit: Nevermind, "Hemispherical cylinder heads have been used since at least 1903; they were used by the Belgian car maker Pipe in 1905[4]], the Peugeot Grand prix Car of 1912, the Alfa Romeo GP car of 1914, Daimler, and Riley. Stutz built four valve engines, conceptually anticipating modern car engines" (Wiki)

 

looks close enough to a hemi for me.

 

As pointed out, called it basically a sales tactic. It's a trademark, easier than saying "an engine with hemispherically shaped heads."

My point exactly. A true Hemi is just a name. Just like the Charger being brought back and the Challenger, they both are still the true cars, being that they mostly are just a name. However, some certain bodystyling does go with them.

But none of them have the Hemi, as a Hemi is a trademark of Chrysler.
