Well, I know the MM engine is a cammer. But is it a hemi? My future son-in-law is a MOPAR freak. He has several. Anyway, I saw him at Christmas after listening to the MOPAR talk for a while, I asked him if he would like to look at the engine in the MM. It blew his mind, it looks much large that the 440 in his vintage MOPAR. He asked me if it is a hemi and I don't know the answer.
 
no. hemi's have a 2v set up where the intake and exhaust valve arranged vertically in the heads combustion chamber, and not horizontally like a normal 2v engine.
 
Hemi refers to hemispherical combustion chamber which is in the head, hence hemi head,
I do believe the dohc 4.6 is a hemi.
 
"Hemi" is a trademark, so no, the 4.6 DOHC is not a Hemi.

But yes, the combustion chamber is hemispherical.

but the valve arrangement isn't and that's what makes a mopar hemispherical head a "HEMI"

so technically its a hemispherical head but not a mopar "HEMI" type head.

and the shape of a 4v combustion chamber looks nothing like a traditional hemispherical chamber

I was watching an episode of Barrett Jackson and the announcer was talking about our 4.6 cammers and how physically big and impressive looking they are. Nice.

They take up too much space for too few cubic inches.

So the marauder engine is a semi-hemi ;)
 
I miss my MM...Hemi or not...

My MM had much more power than my current and new Hemi...but a V-8 is a V-8 :)

Purchased a Durango R/T last Friday..a whopping 310 miles on the odometer so far...few mods coming.
