Thanks for the responses. Yes - they are engine dyno numbers. Mileage isn't so great - it's about 6-7 average. If I keep it under 63 mph on the highway it gets about 11. When you surprise a Mustang GT the mileage is pretty bad....
I'm not sure what it's called but we put a transmission modification in from Ford - 1st and 2nd are really short and reverse is half speed - it's great for backing up horse trailers. (That's where the overfences name comes from)
Thanks again for the replies.
