Had an old Toyota P/U with a SBC in it. With the original rear-end, it wouldn't get over about 80-85 MPH, but it'd sure get there in a hurry! That i-Force has a LOT of power, but you don't have to use it all... I just prefer to! Another cool option would be the 4.0 V6 that came in the Cruisers/Tacomas. My Cruiser pulled boats and campers to Arkansas and Kansas from Alabama umpteen times with no issue, AND, if I could keep my foot out of it, 23 MPG was possible. Believe I got 24MPG on the way home from Florida once, but the wifey drove half way, and she does the speed limit.
