    a 97 7.4L MIE was rated @ 310 HP....it should be a GEN VI block.

    Re: 1991 to 1997 7.4L Engine Swap

    no knock sensor used with the TB-IV ignitions.....

    If you oil pressure switch is screwed into the water jacket, it isn't doing what it is supposed to and the horn/buzzer will actuate....

    Re: 454 XL TBI Stalling Issue

    I missed the sensor unplugged nugget....and its the default value used by the ECU.

    Re: 454 XL TBI Stalling Issue
