oil pressure

I was thinking that to oil being in the exhaust. I got to finish up the brakes. Motors in a 66 dart gt and tell u what rear wheel cylinder are expensive. But I need to drive it. Just sitting on jack stands and running the motor is not good. Need to really brake in the motor than see if it still acting up. Go all day then I will be scarred to run my motor. Thanks you all for your help. If y'all want to see I being broke in go to YouTube type mopar 360 450hp. it's the one with black intake and red and gray valve cover on the ground with green water pipe sticking out.
