I read through the thread, I incorrectly grouped you with the guy whom said R/Ts have "special" heads...But your frist post was the best one...If it's pinging, it needs higher octane, even a Ram needs higher octane if the Plenum is leaking.

BTW...Here's my Dakota...

Can I post pics of a Dakota in the Durango thread....

 

that is a nice looking truck (yes you are allowed to post pictures, we just like to keep the information in a thread relevant to the origional post or related in such a way that it can be followed and helpful) i assume is strip only??, what kind of power you putting out and exactly what is done to the engine?

Nice wire work. Shows you care about your ride by the cleanliness of the wire grouping.

 

Got proof/pics...Got a part number...?

No.

Gee I wonder why?

EDIT: Post a link, a link to anything from anywhere, proving a stock 2000 Durango R/T with a Magnum 5.9 engine came with anything but stock Mopar Magnum Heads....BTW, What was the valve size of those Durango heads?

 

I have heard the same thing at the head shops being Mopar Performance R/T Heads, however I could never find them when looking?

 

Yep why as a matter of fact when I get to the shop tomorrow I'll pull up the records and I do have part numbers and pictures. They valves were 2.02 intake and 1.60 exhaust.

Edit: Excuse me this was only included on the 2003 model R/T. Check this website, it says about the Dakota but all I could find in the time I have to search on it. Pics will be comin tomorrow.

His posts are in this case more informative and correct than Whitewidows at least on this topic. I spent two hours looking and could not find anything about a special head for any RT model. There was a Magnum RT head but it was a performance part available from chrysler not installed on any factory vehicles.

You Hydra need to follow your own advice and keep things clean on here.

 

I`ll also add this, depends if your motor is stock,,,,,,,if stock yu can run 89 and down ,,,,or with a SCT you can pick with octane tune you`ll want to run. I still have to run 94 or higher in mine ( modified ), she pings at 91/92 , it just depends on what you are running, or want to spend of fuel.

 

Here in TN the highest we have is 93 octane!!
