The older regular 4.7L was 235 hp 295 lbft. The newer 4.7L is 310 hp 330 lbft. Not sure what the older HO 4.7L was rated at, but it is less than the new 4.7L for sure.

The new hemi's usually dyno ~300hp peak. They are rated at 390hp at the crank.

I've seen a few 2008+ 4.7L dyno's and they are pretty consistent. With the tuner it really helps out.

So did you ever do cams?
