This is my first van. Got it April 29th 2008 It got a 350/350turbo tranny.600 Edelbrock carburator and Eldelbrock Performer Intake. New Exhaust Manifolds.Gets about 12.5 mpg's currently, Loaded or empty. It does have new rims with Wider and Lower Profile Tires tires. the speedometer is off, Im pretty sure its because of the rims and tire but not sure.
