RE: 7.0 Hemi?
 

I have seen and heard of more engines with variable valve timing and that would be awesome to have.

RE: 7.0 Hemi?
 

I posted a 7.0L/426 Hemi question here a year ago as a"wouldn't it be great if...." kind of thing. Just daydreaming at the time. A 7.0L/426C.I.D Challenger w/true Shaker hood or a hood scoop like old Challenger T/A would, IMO, be the biggest 'top that Chevy and Ford' ever.

RE: 7.0 Hemi?
 

I work for a dodge chrysler jeep dealer. Ive heard a couple different things. One, is that the R/T challenger will feature the 6.1L engine, instead of the normal 5.7L hemi. Then the SRT challenger would eventually feature the 6.4L hemi, Producing 500+ hp. While that would be nice, I dont think they will do that.

As far as the 7.0L Hemi.... John Hennesy's tuning company makes a kit for the srt8 jeep grand cherokee that bores the regular 6.1L hemi out to 7.0L. Ive never seen one race but if you do a search in youtube for a 7.0L grand cherokee, you will find a vid of the engine running and reving. Sounds nasty. I think the name of the mod is the Hennesy 600 or 650. I think that dodge would have trouble putting such a big engine stock in a challenger, as they are already having problems matching a 6.1L hemi to a manual transmission.

RE: 7.0 Hemi?
 

yeah, ive seen quite a few of the "new hemis" turned into 426 hemis...there was a display with one at the mopar nationals, in a 70 cuda, IIRC.

RE: 7.0 Hemi?
 

I know I have heard RUMORs that the updated 5.7L HEMI offered in the trucks will offer more than 2 valves per cylinder. Regardless, I have serious doubts that they will offer a 7.0L HEMI. This would probably be very close to the 600hp range and would threaten the Viper's sales. The 6.4L is a very likely possibility but I have serious doubts about there being a 4 valve per cylinder 7.0L offering. It doesn't fit with the category of the car, I would first expect a supercharger. It would drive prices up even further to build such an engine. The fuel consumption would be terrible (unless they finally give it taller gearing and put the Challenger on Jenny Craig).

Now that is funny.

And here she is.

RE: 7.0 Hemi?
 

LOL! Talk about taking things literally. Doesn't seem like Jenny is doing too much for the Challenger's weight, in fact, it appears to be a few ounces heavier now that the photo is on it, but I don't think that Jenny would appreciate the other way literally. Although she likes to look slim, I doubt that having a two ton car laying on top of her would help her figure in the way she would want it.;) Splat! :D

RE: 7.0 Hemi?
 

I'm pretty sure four valves improves fuel economy, and will help with emissions, also. It makes sense.

They would use the same Tremec as in the Viper, which is good for 600 ft-lbs. If GM is going to 600, why shouldn't Chrysler?

RE: 7.0 Hemi?
 

First, I'd like to say hello to everyone.

secondly, for the 2008 challenger, there are going to be 3 models DEFINITELY released, one with an 8 cylinder 6.1 liter, the 2nd with a 5.7 liter, and the 3rd with a 3.5 any other options won't be out til later i'm assuming...? look at magnaflow exhaust's new offerings for the 2008 challenger, they've already developed an exhaust system for each of these cars. i always read everyone's post on this website arguing about whether the 6.1 and 5.7 will both come out in 08, and no one ever mentions the engine size for the "6-cylinder model", other than stating it's a 6 banger. so now we have some fact...

RE: 7.0 Hemi?
 

And just to back that up, so no one thinks i'm putting out rumors, here's the link to the new mangaflow exhaust systems for those 3 engines.
