I'm going to put a mechanical gauge on today, just to verify. Also I'm going to make sure that the sending unit wire isn't shorted somewhere as well, beats dropping the pan. Got everything back together and to this point at the end of the day, so was looking for some insight before I started guessing. On the 6 qts., there is a lot of discussion on 5 vs. 6, oil passage modifications etc. When I first got the car, changed the oil 4 + 1, and the stick read 1 qt. low. Searched a bunch of forums and came up with the 5 + 1 answer. Most of the folks that rebuild theses motors do some of the oil pressure mods, (which ones always a debate), some add HV pumps, (again a debate), and always crank scrappers and windage trays. The extra qt. is an easy fix for the front sump configuration, not so good for horsepower.
