I had 3.73s in my 98 V10 E4OD. It drove like my Mothers mercury station wagon. Now my 07 V10 has 4.10 with the 5R110 and it makes all the difference in the world.
The V10 is a lot of high tech drive train for the van when you consider this body has been unchanged since 92. In 1992 you could get a 4.9 L inline six. Can you imagine that as a SMB power plant? It would be slow going.
