Points to valve seals and guide wear. but won't effect your oil pressure.

If it smokes on start up the valves seals are bad. They're so bad they've hardened, broken apart, fallen into your oil pan and are plugging the pick-up tube screen.

Wow, an OP reviving a 5 year old thread Carefully remove the main caps, take lots of pictures and post them up here. Don't mix anything up or drop it yet. I'm assuming you don't have access to a bore mic and calipers to measure your clearances. You could use some plasti-gauge and see what the clearances are, although this isn't very accurate. You could measure, get new main bearings, re-measure, and they should at least be tighter. I'd put a new oil pump in it too.

wow it has been 5 years I pulled the motor out back when I had the oil pressure problem and dropped in a temporary motor, now the temporary motor is needing replaced. since it was worn out when I got it. but this 360 is a good motor and I didn't want to screw it up. I have owned it since it only had 30,000 miles on it. now I need to fix it and get it back in my truck. I don't have a bore mic, I do have a cheap set of digital calipers. I will pull the caps off and get pictures, I will mark the caps to make sure I get them back on the right place. probably tomorrow. thanks

Old Quaker Sludge oil used to cause lots of that years ago. Gotta love the old paraffin based oils.
