With the relatively light truck you are working with you should have no problem hitting 20 mpg if you can manage to stay off of the accelerator. That was always my problem after a swap, they were just too darn fun to drive mildly enough to see what kind of gas mileage they could get.

Toss a turbo or two on there and you can pretty much keep the same MPG you were getting cruising down the road but have a great power increase when you want it.
