Thanks for the advice guys,but I already put it in when I rebuilt the motor.Got a new one in a trade for some stuff.I guess I'll change it when I put the tubular front end in.Until then,on a high miledge motor is it normal for the oil pressure to drop below 30pounds hot?It stays at 40 then slowly drops off to 28-30 while sitting in traffic.I have about 50-55 crusing,and about 60-70 in the throttle.
