i built the motor in my sig. about 1/2 a year ago and put a mellings high volume oil pump in it. the motor was intended for a 71 truck and it had a different oil pan.either a front or rear sump, i forgot. anyway i saw somebody type that with the stock oil pans that the high volume pump would suck all the oil out at high rpms and screw my stuff up. is this true and if so, how much bigger of a pan do i need
