Today's Chrysler Hemi's aren't really hemi's, they don't have hemispherical combustion chambers, instead they have closed chambers which is actually what's called a bathtub head and run flat top pistons, this engine has flat tops but that's because it's a cutaway of a highly boosted top fuel nitro engine, they have a mechanical compression ratio of around 6.5 to 1, the blower is what gives them the effect of high compression. The stock street 426's had domed pistons to get the mechanical compression they had which was somewhere up around 11 or 12 to 1 give or take, I can't remember exactly what it was. The new engine's aren't Hemi's but since Chrysler owns the trademark to the name Hemi when it comes to anything automotive they can apply it to anything they want, they could put it on the air cleaner of a flathead engine if they wanted to.

Some old Ford's had hemi head but didn't call them that.

Citroën to, for decades.

About 1948, the Hemisherical combustion chamber was an effort to have more complete combustion without leaving the carbon buildup in the valves and quench areas. The first Hemi heads were put on straight 6 test mule engines in the laboratories at Chrysler. They never saw production or use in a vehicle. It did exactly what the Engineers were trying to accomplish and in the course of this more power was easily obtained with no other modifications. A single overhead camshaft was also drawn up but not produced as the casting and machining would cost far more than they wanted to try and pass on to the public. This technology was then put into production on the newest engines in the Chrysler family. The Polyshpere 318 and the other obscure displacements in that genre borrowed some of that tech. Those Polys were physically huge for their displacement. You'd swear that 318 was a 383 the first time ya saw one in a 66 Charger or a 1/2 ton pickup, not knowing what it was.

I am still in awe that the E49 code 265 engine in a production Valiant without either Turbocharging or mechanical supercharging, on carbs alone, was pushing out over 300 HP However, as a fellow Australian & actual Hemi V8 owner, I can assure you that since both intake & exhaust ports are on the same side of the head, there is no way that the 215, 245 & 265 Australian "Hemi" six is in any way an actual, bona fide Hemi engine except in name only. It's an awesome engine design to be sure, but it's not a real Hemi, which makes the E49's achievements all the more incredible. [Incidently, the more streetable E48, & previous year E37 & E36 engines were almost as good too.]

Thanks for the info man !!

So that's why the hemi is available for regular purchase.

I'd imagine the giant heads also made having huge intake and exhaust runners easy along with a more efficient combustion in the chamber

Great Stuff ❤Love Them😊

Just think if they had cast that engine in all aluminum. That's what it really should have been. I think the 426 Hemi weighed something like 800 lbs., holy waaa...

The hemi was sometimes used for air raid sirens.

Had a 78 Toyota Corolla w/ the 2TC 1.6L with this combustion chamber design. Even the CHILTON'S manual (nominally superior to HAYNES) had on the car described it as HEMI. SURE! HEMI is "brand" but most forget it's also a design layout.

I instantly think of "hemisphere" Thanks for playing

The First Hemi! "The Pratt & Whitney R-2800 Double Wasp is an American twin-row, 18-cylinder, air-cooled radial aircraft engine with a displacement of 2,800 cu in (46 L), and is part of the long-lived Wasp family of engines. First flown May 29, 1940"

That looks like a museum I would like to visit.

Richard Petty famously drove these cars with Hemi engine

Mitsubishi Australia worked with Chrysler to develop the 6G family of engines which had hemi heads on them. They were 3.0L, 3.5L and 3.8L mainly used in Mitsubishi Patrol and magna (diamante) variants

I believe the dual overhead cam Ford 427 also was a hemi (by design, not by name).

Aussie 265 Hemi six still a fab motor

Fire Dome is bad ass.

My previous motorcycle was a Yamaha XV1900 Stratoliner. Its 113ci V-twin was actually a Hemi engine, but due to Chrysler's trademark on the Hemi name, it was never advertised as one.

Hemi are legends. I only wished i own one..😊

The 426 is a big donk !

Guess what engine is used in every Top Fuel dragster even to this day. A modernized, lightweight version of the Chrysler Hemi. Produces more reliable power than any other engine.

When I was in high school, I put a Dodge 241 Super Red Ram engine in my '55 Plymouth, replacing the origi al flat-head 6. It ran well, but was far from a "muscle car".

Joe Dirt knows.

Buick in 53’ used a very similar domed piston and head combo that looked like a wedge. They used them in the Nailheads all the way to 66’

I think it's called... Whaaaaaaaaa!,.. sniff, sniff,... Whaaaaaaaaaa!... 😂😂😂❤

It was the Pontiac 455 that put the hemi back in the looser circle

The red one almost looks like the black on black mad max car

Don't quote me on this, but a while back i came across a YT video stating that toyota was the first to produce a "hemi" engine. But, dodge has definitely made the hemi a lot more well known, and recognizable

It was actually originally manufactured as a tank engine for WW11 but wasn’t sorted out in time as the war ended so Chrysler installed them in production cars

And now nothing on a stock car is stock. Miss the old days

Almost every small motorcycle engine I’ve worked on has a domed head.

"Yeah, it's got a hemi"

full hemi and quattro Hub 😅😂❤❤❤❤thats goes over sll from the complett ppm

The first Hemi engine was infact buildt by Peugeot, in the early 1900s

Excellent. Concise intel.

Even in 1968 six mpg made them at least somewhat impractical -

ITS THE HEADS !

The hemispherical design of the combustion chamber is not necessarily only in the hemi. But once the name and trend caught on there were no chances other engine makers would try to sell there vehicles on this engine design alone. However given the efficiency, it was almost standard engine design at one point. However not remotely limited to Chrysler and they're second rate engineers.

331 Red Ram Hemi ❤

When think of Hemi i think of lifters ticking

Fun Fact; bunch of companies had Hemi(spherical) engines, even pretty standard unsporty Toyotas, because it simply became the commonplace engine of the times until pentroof superseded it The difference is Chrysler owns the "Hemi" trademark word, but the specific old technology for what Hemi actually is was used by most all companies that existed long enough ago These days there's little point in using them unless you plan on forced induction that needs low compression, something that's less necessary with readily available modern higher compression stable fuels

Hemi engines existed before Chrysler & ford, alfa romeo used them since 1910, and they didn't invent them , they are older than that !

I think the only vehicle I ever had without a hemispherical combustion chamber was in fact a Dodge. People think there's something special but nearly everybody has been using them for a while

When did McCauley Culkin become an automotive historian?

You forgot to tell us that the first Hemi was in a WWII mustang fighter. 400 mph.

The first hemispherical combustion head was designed by Alfa Romeo in 1933.

Lancia Fulvia v4 engines are also hemi engines. But are quite small.

And other car manufacturers had hemis as well

Funny in your video the intake valve doesent even open. Also there is a whole lot more of mechanical science involved with that engine - & hey you forgot to mention the 392 legend -

Chrysler wasn't the first Hemi, Pipe company in Belgium had the first in 1905.

hemi is not an acronym. hemi is just a reference to the shape of of the combustion chamber.

They also went by the name firepower

The boss 429 was really the only true hemi built it had hemispherical pistons also i know this makes mopar fans upset but its true

I don't understand why people don't mention the even more rare in my opinion, better Ford him. That's something I'd like to hear about
