an I'm not really sure what I can tell you about you smoker that anybody else has already mentioned. Sounds like seals to me too, but might be the oil rings too. Just a comment about the guy who said all 327s'smoke.........NOT! I have a 350 horse, stock, in my '70 chevy 1\2 ton in front of a 4 speed, and it has (known) 250k miles plus and still runs great and still no smoke. Yes it does leak a little, but no smoke. I have had 2 in other Novas and they did'nt either.
