1970 302 smokes heavy when it starts up???
after a few seconds it smokes hardly at all. Is that valve seats or could it be something else? It will blow a pretty good puff if I get on it pretty hard after it warms up. thanks in advance for any help. Also smokes more from the passenger side than the drivers side.
