Years ago, Chrysler installed turbo charged, 4 cylinder motors in the Dodge Caravans. There was a story, last year, of a guy who runs a faux wood paneled Caravan (one of the turbo charged ones) at the local drag strip and beats the snot out of the Camaros, Mustangs andjust about any wannabes that go against him. He has a site on the internet and talks (a very smart guy by his review of how he tweaked the motor and trans to get the performance) about the van. He chuckles about how he gets giggles as he stands in line awaiting his turn but looks at the guys he just flogged with his little van. All I can say is hahaha.
But you are correct. Wasting a V-10 on a Caravan? Who has V-10's laying around like this?
