Could it be true?

[srm-rt]

This is what i found on a web site article. Could it be true?


The 2008/2009 Challenger SRT will, in fact, be powered by a 7.0L hemi engine - marking the return not only of the Challenger marquee, but also of a 426 cubic inch displacement engine. The engine reportedly will be based (loosely based) on the current hemi engines, but will feature four valves per cylinder with dual-independent variable cam timing. Reportedly, this step was needed to best the Chevrolet LS7 engine, which is slated for the 2009 Camaro redux. Performance figures for the 7.0L hemi have not been disclosed yet.

If this is true, this could very well be what the Dodge camp needs to compete with the beasts that GM is churning out these days.

That's the first I've heard of a 7.0-liter Hemi, and I really don't think that info is factual - but you never know!

We have been told initially the 6.1-liter and 5.7-liter V8's will be offered, and that perhaps in a year or later after those a more powerful Hemi will appear.

There are rumors everywhere about an increase of displacement! The hard spec's sound sweeeet! There is another active thread that indicates there is no HEMI design possible with 4 valves per cylinder! But even so I think 4 valves is the way to go, the HEMI is just not good enough for todays emission standards.

I dont know if that is true but it would be cool. But I do know, is that the LS7 is suppose to go into the new corvette, not the camaro.

Hmm, 4 valves versus two valves. The advantage lay in increasing the engines air fuel intake into the cylinder. Typically 4 valve heads show advantages at engine speeds above 4000 rpm's. It also increases both valvetrain weight and complexity thus costs increase substantially. Chrysler has typically 'shyed' away from small displacement high revving DOHC V-8 engine design for a reason. The vehicles they manufacture are Heavy and require a sustantial amount of low speed torque to improve both driveability, and efficiency. It will be interesting to see which way they turn. My money is on a long stroke, 2 valve, variable cam timing,(Ala SRT-10 Viper 08), for the same 6.1 size,(remember we want this car affordable it's an American Muscle Car classic), for 450-475 H.P. the same in torque. Who cares if it's few H.P. down from the competition, it will be offered with many aftermarket parts and tuning modules. In 1970 Chevrolet touted they had the highest H.P. rating with the LS-6 450 454. Who won the Nascar and NHRA Championships that year? Team MoPar did with the 426 Hemi that "only" produced 425 rated H.P. see where this is going? Have faith bretheren. Ma MoPar wont disappoint. Count on it!

The trend lately with motors is a big bore and a short stroke to allow larger valves, and better breathing. I just hope they keep the 4 bolt mains and the wicked stock 300 cfm heads, I can build the rest hehe
