I hooked up a mechanical oil pressure guage to my big block and with my homemade oil primer i spun the oil pump on high speed with my drill. I am using a stock volume, high pressure spring mellings pump. I got 70PSI out of each port to my suprise, i thought only one of the ports would have pressure, it is a mid to late 70's 454. i believe the 2 ports are for a cooler? one is really big like 1" pipe thread and the other 3/4". does this sound correct? i need to hook up my fuel pump fitting(turns on pump when there is oil pressure) and my oil pressure guage fitting, so having both of these ports would be nice!
