My brother just bought a '79 Bronco...(I know this is a sac-religous question.) and changed the oil...the beast took 6 or 7 (caint remeber) quarts to get a full reading on the dip stick!!! this really concerned us...what the hell could be wrong....the owners manual said 5....that sounded almost normal...but 6-7?!?! yikes.....anyone know how long a dipstick for a 400 should be??????
