Both my 92 4x2 and 92 4x4 have holley TBIs similar to what you have pictured on them. I believe they are stock, but maybe someone else will correct me.

 

They are stock, and they are throttle bodies, not carbs.

 

i noticed this on my 96 TB and i was wondering the same thing now i know

 

Yea the Holley TB is stock believe it or not :P

 

It is stock and you have the TBI (Throttle Body Injection) where the fuel injectors are in top of the TB as where MPI (Multi Port Injection) have a fuel injector in each intake runner.

TBI was used on the older LA engines and MPI was used on the newer ('92 up) Magnum engines.

 

The picture above is a stock Holley Throttle Body with injectors TBI (Throttle Body Injection). Not a carburetor like mentioned.

The 92-03 V6 and V8's have a stock Holley Throttle Body. Not a carburetor like mentioned.

Just because it is a Holley doesn't mean it is a performance part.

 

I to had been wondering that. When i bought my truck the guy talked like that was a performance throttle body lol. Guess cause it said Holley. Anyways i didn't think it was a performance part and done a little research with no definite answer but now i know.

 

atleast its got a decent name on it if nothing else

 

Lads, correct me if i´m wrong, but Holley does have a performance TB...
