I have a 383 stroker in a summer car that as far as I can remember never did this last summer. In the winter I changed from a 180 deg stat to a 195 deg, went from ported to manifold vac, changed converter, and went from water with water wetter to anti-freeze and water.
When I first fired her up at the beginning of the summer she smoked white till it warmed up. It still does this when I first start it up cold from my garage 98% of the time that I have noticed. If I drive it and is hot out go to a cruise spot let her sit for a while then go there is no smoke. Seems only from stone cold starts after sitting a fair amount of time (over night?) And only lasts say 5-10 mins till engine is warmed up. Maybe just my worries playing tricks on my brain but I sense a bit of a coolant scent too.
I am told a head gasket will get worse as it heats up not better, is this true? Most people say it is just condensation, but I never noticed it before this season.
or the record this is a fairly new motor built by a reputable shop. It is my 4th season running it with very limited miles each year. Here are the specs.....
