Anyone Swapped A 3.7 Into A 3rd Gen Ranger?

That engine is wider and taller than a 302. Even the most basic 302 can make 300+ horsepower and deliver for torque.

Engine swaps for fuel economy is a fools errand IMO. The cost to complete the swap will buy A LOT of fuel instead. Engine swaps are for more power. Be honest with yourself and you'll agree. More power is always more fuel. It takes a certain amount of fuel and a certain amount of air to make a give HP. Be it a turbo 4, V6 or V8 they will consume the same amount of fuel and air to make the same power. Only off power throttle can offer gains in economy.

Yes, this, and don't forget the headaches and hassle of getting the electronics to work. That's probably worse than the physical swap.
