At what rpm, and what about torque?

It would suck if they get rid of the 4.7L right after they are able to squeeze some power out of it. Imagine if they invested in the 4.7L like they did the hemi; VVT, MDS, and the variable intake runners.

While it would be a good investment, they have more pressure to be more "eco friendly" and compete with Ford's V6 market. And with the V6 getting bigger and more powerful it leaves little room for the 4.7 to thrive in the big truck market. You start advancing the 4.7 and then you start encroaching on 5.7 territory at some point, and that won't go over well. Same reason why you can't ge a luxurious Tahoe, that's Cadillac territory. Jeep won't offer a truck (yes there is a conversion kit) in general because that's Ram territory etc.

I don't understand why they didn't focus the 4.7L more for the smaller suvs, and even some cars, and leave the hemi to the big heavy trucks, big suvs, and the special models like SRT, RT, etc.

Just seems like a charger with the 4.7L would move out quite well. They pretty much only put the 4.7L in the ram. Then there were a few in dakota's(which was already a dying breed) and the durangos. I don't believe it was in anything else.

Either way, they still have a great line up of engines all and all...

I agree. Further there is now likely the small diesel to be thrown into that mix.
To the encroaching on the 5.7L point, i wish they would move to the torqier 6.4L for the trucks.

I have a friend that had a 4.7 and we just did a hemi swap on it. Its pretty much a direct swap we used a wrecked 07 Ram as the doner truck for the new trans and motor. We took the transfer case of his 45RFE and put it on the 54RFE and bolted it in. Then shortly after we dropped in the new motor with a sidewinder cam installed along with a 6.1 timing set. Just waiting on the wiring harness to come back and route up the exaust. Its gonna be a beast!
