So a guy was bored and decided to start doing some calculating. I’m on my second fill up since the engine swap and I’ve been pushing it a little on the hard side, not beating it, just making sure there aren’t going to be issues that rear their heads soon and I’m already getting OVER 18 MPG. Not bad for a 3” lift, 4.10 gears, 31s, a 32 year old brick shaped truck and a 17 year old kid! This truck never ceases to amaze me.
