Just so you know, you want a 50mm for that 5.2 Durango. So unless the guy on ebay (link that was posted) , who is the member here I was talking about, also has some 50's. I'd wait for fastman or go with HeyYou's suggestion.

 

Agreed, that is what I was looking for.

 

What the O.E.M. 48mm?

 

The OEM TB is tappered, and I can't recall the #'s at the moment.

 

Contact that guy on ebay or the guy HaaaayYou suggested.

On a side note, the guy on ebay has the same name on DF.

 

Should look into the Big Gulp ones. They seem to flow the best compared to the charts.

 

I think it might be too much flow for my little stock 5.2

 

I've got the Holley TB on my 5.2... probably a little too much for a stock 5.2, but I'm adding more mod's as time goes by, so I'm hoping it will be a more appropriate size when I'm done.

I got mine from Amazon, on a price drop @ ~25% of list (75% off).

 

Yeah and I think that big gulp was a 53mm too. Did the 52mm give you any more top end and cost low end torque?

 

Don't mean to thread jack but this is a curious topic.

What would some supporting bolt on mods be to get the most out of these larger throttle bodies; intake, plenum, SCT, and full exhaust?
