Al,

I just went through this issue with my 1930. However, there was a paper published in the Restorers Journal addressing the issue. The author states the motor should be out of the car on an engine stand turned upside down with the crankshaft rear flange up. This eliminates the possibility of the crankshaft moving horizontal as may happen if the engine is still in the car as you turn the crankshaft. I placed my dial indicator mag base on the crankshaft flange. The dial indicator touched the flywheel housing. I made sure the two "original" brass shims were in place under the accelerator peddle bracket. All 4 flywheel bolts and the two peddle bracket bolts were torqued down to 55 ft-lbs. I measured the run out only between the oil pan rails along the engine top. Mine was out so I played with the shims only and brought the housing to within 0.006in. I rechecked the measurement the next day to see if there was any movement. All was well. Don't forget to install a new flywheel gasket before you start your measurements. Download that article if you can. It is on the web if you Google the subject.
