i took the picture because the car was pretty clean...and i wasnt positive that there was NEVER a factory hemi wagon...i know that the "max wedge" cars were offered in wagons...but the 426 hemi didnt find its way into a dodge until the 64 or so for stock eliminator, right? and 66 was the first real regular production hemi cars with the charger?

I got the rich man's engine before you had to be rich to get one....
Well it was pretty expenaive for the day. any of those engines back then were screamers whether they were rich man's, normal man's, or poor man's.

The "Hemi Engine" is a design of internal-combustion engines in which the cylinder head's combustion chamber is of hemispherical form.


The hemispherical combustion chamber design puts the intake/exhaust valves in-line, rather than side-by-side, allowing for better flow of air through the head (although the inlet and exhaust valves are not simultaneously open and there is no continuous flow).

Chrysler introduced a modern Hemi in 2002. This engine is not a true hemispherical head engine; it has a polyspherical combustion chamber, but retains the Hemi's traditional inline perpendicular valves. It is available in two sizes; 5.7 and 6.1 liters. Some versions of the 5.7L, including most 2006 production units, utilize a variable displacement technology called the Multi-Displacement System (MDS) to improve fuel economy. Also, at the 2005 SEMA show, Chrysler unveiled a 505-horsepower 6.4L HEMI which will be available as a racing crate engine and might find its way into production, perhaps with reduced horsepower.

Bottom line are the new Hemi's are not like the Hemi's of old except the inline perpendicular valves. Apparently, the shape of a Hemi combustion causes a lot of excess gases that the EPA has a problem with. But what a great marketing tool because just saying Hemi conjures up in the mind a muscle car that has no equal.

You are correct in that the Hemi first was a race only version in '64.... the first street version was made available in '66. There were a handful sold in 4 door sedans in '66 & a couple in '67, but never in a wagon, and none past '67.

woo hoo! i got one right!

also, i saw a new 6.4 at the NAIAS, and there was a 70 challenger with a 6.4 in it..

That Challenger has been in a few of the big magazines. Looks pretty nice.

I have to go with the 440 -

Even though big blocks period are getting crazy, you can still find 440 pieces parts around pretty easy.
Heck, I'm lucky enough to say I've had a few 440's ( only this one in a good car though ) and the one thing
I can say is they have always been stout with little mods.
Set it and forget it 440. If you like the garage and have deep pockets go Hemi. ( not that I have Hemi experience but heard they could be finiky )

I think the MDS technology is going to stay only with the 5.7L engine. I heard that the higher compression and other technology could cause some possible reliability problems. Make no mistake about how I feel about MDS being offered in other versions. As long as it works I'm in favor of it.

One for a 440 here, though I'm a little biased. But the 440 beats the HEMI to the legal street limit (60mph). Easier to make hp at less cost, easier to maintain (HEMIS are a pain in the arse to get running right, all the time. 426 HEMI has the shock and awe at car-shows, but for me the 440 is the best allround engine 4bbl or 6. The 440 also weighs a hell of a lot less, which in a way makes up for some of that hp.

You are right about the lower speed acceleration being better on the 440 vs. the 426. It depends on what you value more.
