HO 4.7L or NOT?

[afgunn]

I recently acquired a 2004 4.7L Dakota 4x4 and the throttle response and power of this engine "seems" to be noticeably more than the 2005 4.7L Dakota 4x4 I had a year ago. The VIN build sheet from the dealer does not list the engine as HO (I do not have the code with me) but as "xxx - New Generation 4.7L Magnum". Does anyone know how to definitively tell whether I have the HO engine or not? TB part number or intake part number?

Thanks!

4.7 H.O. wasn't an option on the 04 models.

Thanks! Yep, that is what the dealer said too! I will continue to look to try and see what the differences are. The exhaust on the 04 does not have the "huge" muffler? that the 05 has. I guess the difference could be in the fuel/air curves as well.

Is the 2004 service manual available on CD or online anywhere?

There's afew things different from the regular 4.7 and H.O. Cams, intake, etc, etc... You can search it online if you want too.

I do have a 2001 service manual in pdf format if you would like, it's free and online. Wont be much different comparing the 01 to 04 models.

Thanks all for the info. Thanks for the offer on the 01 Service Manual but, I ordered a 04 Service Manual on CD the other day -- looking forward to getting it!
