Grab the Fastman throttle body for a 2001 model. As for the 2005 parts, let
me look at the intake more closely at the dealership as there are some minor
design changes on the intake manifold: mounting brackets mainly. As for the
valve covers, yes...you can blast/polish/paint them.
On the tools, there is a wedge tool that you can use for holding the
tensioner in place, but if you're really careful...the job can be done
simply by using zip ties to hold the chain to the cam gear (one side at a
time).

Subject: DML: 4.7L HO parts
I have a 2K 2WD club cab with the 4.7L engine and automatic tranny. It has
85k miles on it. Airaid intake, Transgo reprogramming kit, Flowmaster 40
series muffler and dual rear exhaust. I am looking into the HO cams and
intake, which (according to various accounts on the web) add anywhere from
20 to 35 hp.
In my research, it appears that the HO intake is hard to find, and any
late-model 4.7L intake has most of the advantages of the HO intake. So it
looks like I want the following parts….
2005 INTAKE MANIFOLD, Dakota, 4.7L $59.79
2005 CAMSHAFT, Dakota, w/High Output, Right - 4.7L - 4.7L $102.78
2005 CAMSHAFT, Dakota, w/High Output, Left - 4.7L - 4.7L $102.78
Now, I think that the IAT sensor changed in the way it was mounted, but
electrically it still connects the same. So I’ll get this part:
2002-2003 TEMP SENSOR, Dakota, 3.7L and 4.7L $6.41
The 2000 came with 65mm throttle body. Later OEM throttle bodies are 68mm. I
can get this OEM throttle body for what seems like a great price.
2005 THROTTLE BODY, Dakota, 4.7L $87.40
Or would I get a decent benefit by going to a Fastman-modified ($180+core)
or BBK aftermarket ($300+) throttle body?
Other than the special tools to make the job easier, is there anything else
I should get before I start? Gaskets? Quart of JD?
And finally, has anyone painted the magnesium valve covers on a 4.7?
anything special to worry about? Can I blast them and spray them with
hi-temp paint like a steel cover? Can they be polished?
Thanks,
Ned Buckmaster
