A higher amp alternater will not change full economy just because it is larger. If the amp demand is lower thats all the alt will put out regardless of the size. Now if your demand is higher then 136 amps then it will put out more amps, if it is lower both alts will put out the same and use the same horsepower. Personally I prefer the larger just to have the extra reserve or are using the truck to jump start another engine and you need to charge the other battery some first.
Remember not to talk bad about farmers with your mouth full!
