V8 (5.2) swapping a van

That looks like a Conversion Van, as in finished off inside with "plushness." We had a Chivvy G20 back in the 90's and they are pretty heavy. That had a 350 and don't think a V6 would have made me happy, LOL. I don't know how much different fuel mileage would be from V6 to 318. If it is not a conversion, then ignore my rambling.
