Questions about a 2006 5.7
Just watched the Hemi comparison episode of Engine Masters again and the Eagle motor did not have the VVT locked out. They spent a fair amount of time talking about how they messed it up and had to replace valves learning how to tune the VVT correctly.
Also of note, they agreed the 2006 5.7 they ran seemed down on power. They couldn't say why but they figured it should have made 20-30 more than it did but just a guess.
It's too bad they didn't leave the OEM intake on the '06 motor and compare that. I think it would have been much more cost effective and a much better comparison. Even if the '06 didn't make the same power, it would at least have been cheaper (I think). All the stuff to run the carb was like $2K.
