    The intake on the 94 runs better low end torque but the throttle body is in a crappy spot. Being in an F100, that's not as much of an issue. If I'm not mistaken, the 98 runs on EEC 5 rather than the 4. Better choice there if so. I am using a 94 with actual Cobra heads and intake and no IMRC's. I say whichever engine has the lowest miles or looks the best if you are just dealing with longblocks and no EEC.
