Knee jerk reaction

Copperhead I see a fair bit of Ford flat head stuff in that pile, The connecting rods will have forging numbers, from these you should be able to identify what you have.

Lots of interest in those old ford V-8's so you should be able to market most if not everything.

A few of the starters in the pile look like 352 and 390.

To do a quick test on a generator put 12 positive volts to the armature terminal with a ground to the case if the generator motors ( become a motor ) it will generate power to charge a battery, This procedure will also polarize the generator replacing the residual magnesium which can be lost with age or rough handling - excessive bumping or knocking about ie: dropping..

Opps forgot those early generators will be 6 volts, be sure to check and use the proper voltage for testing
