Thanks, I wanted to know something about the difference in the 3.8 and the 3.9... That explains why SuperChips has these specs on their dyno chart...

This is the dyno chart, you need Adobe Acrobat Reader to read it...

I would had thought that a engine that is stroked a little would produce more torque and I would had expected it to produce the same amount of torque as the Freestar without only producing the same torque rating that the 3.8 produces.

But thanks again...
