Good points, but none of these "advantages" has anything to do with it being a "hemi." The Chevy engine with the wedge head is getting practically the same power with a smaller, lighter, and simplier design (1 plug, simplier rocker arm system, etc).For a person buying a vehicle today, growth means almost nothing. And if I they want a bigger engine, then Chevy already has the 7 Litre LS7 (505 Hp). As far as I can see the main attraction to the "hemi" is the ability to claim you have a "hemi." I think it is the triumph of great marketing over good engineering. Chrysler has already been down the hemi road twice before. In the end the disadvantages of the design resulted in the engine being dropped. Even the legendary 426 Hemi in NASCAR race trim was no better than a Ford FE 427. And nobody would claim that a Ford FE was a particuarly sophiticated engine. You also have to wonder about the wisdom of spending tons of money developing a large, thirsty, enviromentally marginal engine at this time in history. On the other hand it has been a marketing bonanza. People I know who haven't considered buying a Chrysler in
40 years, are suddenly interested in Chrysler products again. And I suppose that is what really matters. Still, it just seems to me they made a lot of bad compromises so they could claim the engine was a "hemi" even if it is only marginally one.Ed
