Hey,  just bought a 1977 Z that im waking from a long +15 year comma.  Loloking for guidance as to what i should do and in what order.  Compression check done.  All Cylinder are in the 180s except 1 which showed 145.  I changed all the plugs, oil and filters.  I also drained the old fuel and fuel filter.  Radiator was empty and thermostat had disentegrated cavities in the cooling systme had white powered residue.  Car will only turn over when i jump the starter leads with a screw driver and
