My fuel mileage sucks anyway (my 20r carb is pretty shot) so I'm used to it. LOL. May as well get the better HP and pretend the mileage is the same.
I was hoping to drive the rig down to Joshua Tree next weekend, but with it chugging so bad at 60mph it'd be an annoying trip.
do the swap, you will be pleased, you also need to go to either a header or a 22R twin tube exhaust down to under the cab then into a 2 1/4 inch tube
