Recently picked up a '57 and would like to tinker with it and get it running. Motor turns over BUT when I first went to turn it over it went so far then stuck. Thanks to my boroscope I found the #7 cylinder had some light corrosion in it. I dumped some Kroil in the cylinders and worked it back and forth and now it will turn all the way over and I have used the starter to spin it over some but it does have a somewhat tight spot. Would you go ahead and oil the cylinders some and try to fire it up or should I pull the head and look closer at the cylinder. It is the original 283 2 barrel and was told it was running decent about 10 - 12 years ago. What Would You Do? I've got a feeling I already know the answer.
