Does anyone know if the BBK throttle body thats listed as being for the 1999-2003 4.7L engine will fit on the 4.7L in the 2004 rams? My understanding was that the '02-'07 4.7L engines were all the same, but there was no 4.7L engine in dodges prior to 2002 but somehow BBK advertises the TB for the 4.7L from 1999-2003. I only ask because i want to put a TB on my 4.7L but i don't want to order one only to have it show up and not fit. Anybody have any thoughts on this?
The 1999-2002 4.7L engines had the JTec PCMs... which used a small Idle Air Control (IAC) mounted to the throttle body. The 2003-2007 4.7L throttle bodies came with the NGC PCMs and a Larger IAC mounted to the throttle body.
So you need to know which PCM you have...
If you have a J-Tec then the 70MM BBK throttle body will work with your application.
If you have an NGC throttle body then it will not.
