smoking 360

Dodge Freak,

Ya, I spent about 3 hours, not just tightening, but cleaning the manifold as good as I could get it. It had a dark discoloration here and there mixed in with oil on silver paint. It looks like the gasket is some kind of pressed cardboard. I ran it in the garage last night again and it went about 45 minutes without smoking, so I shut it off. Today, I let it run for about 2 hours. There was no smoke when I first started it, but within a minute or so it started smoking again and never stopped for about two hours. When I gave it gas, it really came out heavy blue smoke. What I don't understand, is why didn't it smoke last night for about 45 minutes at all. There is no leakage around intake now that I got all the bolts tight. It would be nice if you were on to something about the intake gasket. I'll have to find someone to help me pull the intake off. What kind of a setup have you got down there? Do you do much engine work? I went too many years to Ferris. The degree didn't do me a bit of good as far as employment. Appreciate your input!!
