If you are looking at the fake Dodge picture of the dyno run with the 4.7
(the Jeep Powertech engine), it is not accurate at all. The HO engine
produces more HP and slightly less TQ than the current standard 5.9L.

10 hp less, yes. But look at where the 4.7 and 5.9 make their power. The
5.9 also makes 35-40 more lbs/feet of torque than the 4.7 and a lower peak
rpm i.e. more usable power on the street. And the 5.9 has way more mods
available at this point. I've had both motors and I like them both but at
this point, I'd go 5.9 for a performance build.
