You can get a good idea of cam/crank timing by watching the rockers on #1 through a couple of revolutions and watching the timing mark and distributer. If you haven't modified the inner two bolts on the timing cover you have to pull the oil pan and that is a pain! Make sure the carb bowel is full and prime it with a little gas. Stand back and have a fire extinguisher handy! Does a '57 have hydraulic lifters? Are they pumped up?
