Well, it would fluctuate between 60 psi and 20 psi before. Now, it holds steady at 50 psi cold and then between 40-50 psi (depending on revs) once all warmed up.
BTW, I have heard (and looking under my wife'* '04 LeSabre, I believe) that getting the oil pan off the 2000+ H-Body is much more involved, as you have to remove that big bracket beneath the crankcase pulley.
