map or baro sensor on 89 5.0

[shelby2]

i was just wondering what sensor the 89 5.0 has, the baro or map. i recently swapped this setup into a 67 and don't know if the vent on the sensor is supposed to have a mainifold vacuum line on it. if someone knows or can find out if the mass air equipped 5.0's have a vacuum line on it or not i'd appreciate it. my car is running poorly right now and i am thinking it is either that or bad o2 sensors. thanks in advance.
