Re: 38 Twelve. how to compress rings to install ?

Thanks for the info and pic David, The tool did not show up in the Packard Special Tools catalogue which I have. It showed a ring compressor which was for the Six, 120, eight, Super Eight but excluded the 12. I was wondering if you also know the connecting nut torque setting and also the main bearing cap torque settings. I have been unable to locate either of these settings in the Shop manual, Service letters and other general motoring Maintenance manuals of the era. I have the connecting rod bolted together but I have yet to set the torque. I am also curious as to whether I should use the Packard setting or the setting for the Caddy bearings which are fitted. Please advise your view on whether this is relevant or should the crush be about the same anyway. I'm guessing that 55-60 ft/lbs should be sufficient for the connecting rod torque setting, comparing bore/stroke/rpm with the 3.5 inch bore Six and 3.5 inch bore 356 Super Eight motors.
