Actually, it's the other way around- the 13BT lists at 120HP and the 1HZ @ 135HP.
The 13BT is a nice engine but if you were considering a swap you may as well go for a cuurent engine and one that produces the most bang for buck. The 1HZ is a good choice in that respect- turbo it and it reportedly will sing you a wonderful tune.
As for fuel economy- I'm not a tight #'s crunching type but have had many 3B's, a 13BT and now a couple of 1HD-T's and the economy is close. It's within a few MPG's. My 80 is the heaviest and only full time 4wd of my Cruisers and I still can attain a respectable 23MPG. My Bj60 with a 3B was getting approx. 26MPG. Not a big diff to me esp. considering the power gains- 90HP compared to 160HP.
