I have a '57 Fairlane 500 With the factory 292ci Y-block that sat in a barn in Tulsa for about 30 - 40 years and the distributor has become stuck in the block, this means that I cannot adjust the timing at all and due to the location on the distributor I have been unable to get to the housing with anything to try and get it moving. I have sprayed CRC/WD40 at the base of the housing without success so far. Has anybody got any tips to help me free this up free this up? I am going to get some acetone to mix with ATF and try, any/all advice appreciated.
