The throttle bodies are the same so the Fastman will fit without any issues.
Injectors...that's a different issue and there is a difference in the
impedance for the model years. No need to change them out anyway unless the
PCM is programmed for them. Didn't get a chance to look at the manifolds up
close yet - was a bit busy yesterday but will have a chance this AM.

Do different flow rates imply a different ECU/flash? Or would the existing
ECU/flash handle the higher flow injectors without a problem?
On the 2005 parts catalog, injectors aren't listed. On 2006 Dakota, which
lists both regular and HO cams, only one injector is listed, but year range
is 05-07. $33.28 each or another $266.
Fastman for 2001 will fit the 2005 manifold, right? Hopefully, he will take
a 2000 core....
Did you get a chance to look at the 2005 manifold yet, Bernd?

That's correct
I believe the injectors have a different flow rate for the HO
motor....correct?
