Using Oil? A quart/1,000 miles

My 360 engine was rebuilt about 5,000 miles ago by the prior owner. I have reciepts on the professional rebuild. My question is it uses about a quart of oil every 1,000 miles but is this normal? It runs great and doesn't seem to burn oil! There is a small leak only at the auto transmission cover shield that
doesn't amount to anything much and doesn't continue while parked. I checked down inside when I replaced the distributor and all the pipe threaded plugs are in place. The cast valve covers don't leak.
I don't know. Maybe I shouldn't care too much and just keep adding oil as needed.
I'm sure this isn't much help but, my 64 273 uses 1 QT per 1 FULL tank of fuel. Has 70,700 miles though. Doesn't leak, does throw a black spot in the morning during warm up, will smoke a little at 1st take off if cold only. I never see any smoke other than that.
Our 67 with 70 318 uses 1Qt per 2 months but lately thats due to being on ramps! LOL!! Normally will go through 1Qt every 5 FULL tanks of fuel, no smoke but leaves a half dollar spot from drain plug everywhere it goes like my Harleys used to!! Enjoy and Good Luck!!:-D
