I was driving my car yesterday and the smoking got worse. I have a 351w that i built with stock heads and a performer rpm intake, topped off with a 750 cfm edelbrock carb. All of this was like new ordered from PAW. I don't think that I gave it enough break in time; the white smoke is coming from the tail pipes and I think that there is a leak on the headers because it smokes from under the hood and the coolant is constantly low. The temp stays normal (180-190) under the amount of time that i have driven it. My question is what do I need to replace? Am I just looking at replacing the head gaskets and intake gaskets (when i remove it to take off the heads) or am i going to need to do a rebuild on it with rings and maybe bearings? The engine is only 2.5 years old with under 500 miles on it since the rebuild (i can't afford gas, haha) so i can't figure out why i would have blown a head gasket unless it wasn't broken in yet. thanks in advance for your replies
