the other weekend i fired up on of my old junker crew cabs with a 440 in it that hadn't been started in over 2 years, primed the carb and hit the key, it was running with in 3 revolutions and had 55 psi oil press.
If i was you i would install a manual oil presure gauge, see if you can borrow on from a friend. Then see what the reading is on it.
