Maybe they introduced the 3rd gen with the 3.8 in the SWB but found sales so poor that in the interest of streamlining the order process they just dropped it...I remember seeing the 3.8's in the standard wheel base minivans in 1998 when my 1998 Town and Country was purchased. It was in a 1998 Caravan LE. Never drove it though, wasn't looking for a SWB van. But saw the sticker, I was like is that right? Looked under the hood and there was the 3.8. To be honest though I haven't seen one since.
