rebuilt engine smoking question

so i rebuilt my 350 back in november, and put it in the truck in may, ran it for a month and blew up 2 tranny's, got it running sept 2nd and noticed it smoked a little, didnt fase me thaught maybe it was still bearking in,
now the smoke is getting bad, a quart every 16gallon tank,

Problem:
when i first got it running i took it down the road, kept an eye on all my gauges, and without my knowledge it overheated and seized the pistons to the cylinder walls (gauge stuck at 180), cooled down and started back up but it was due to a faulty thermostat, could the aluminum have scored the cylinder walls and basically wrecked everything? or could i be lucky and just have bad valve seals (vortec heads, replaced in rebuild)?

its just making me pretty frustrated spending about 2 grand building an engine to it burning alot of oil

If it ran real hot chances are the rings overheated and lost there tension. I would put a vacuum gauge to it and see how much the needle moves. Chances are it ran so hot it seized, the rings are likely gone. The pistons and the cylinder wall likely don`t look so good either. You may also run a compression check and see what you get cylinder to cylinder. My guess is it`s rebuild time.

If it got hot enough to stop running, serious damage did occure. Time for a pull down. check everything.
