Got it put back together with all these parts. Started right up! Now to drive a bit and make sure I don't lose coolant. Then after a couple oil changes, send out to Blackstone. Idle is still a little rough and hot oil pressure around 35 but I didn't expect improvement since this was just top end stuff. Might do an oil pump at some point, just hoping there isn't bearing wear.

Put new brake pads on all the way around, adjusted my parking brake shoes, and greased the front end. Trying some Wagner Thermoquiet pads this time. I used AC Delco pads last time I did the rears and they made a lot of noise. Hopefully this fixes that problem!

That lists an oil pump, pan gasket and pan bolts. Did you have a shop do the work? If so, it looks like they did replace the oil pump. Edit: that Fel-72401 is the o-ring so that must be what got replaced?

I did the work. I pulled the pan because it had a little bit of sludge on the bottom. So, for good measure (and it was cheap enough) replaced the o-ring and pan gasket even though they were a tad under two years old.
