As others have stated you will not know what you got till you either take them down for a inspection or use them strictly for a parts purchase and anything that's a keeper or a runner is a win win . As for value unknown motors at are a touchy subject when buying them More than half will be boat anchors and the other half might be rebuildable but at what cost.. and motors are heavy and dirty to store and just move around.
If you bought them for scrap weight you could not lose any real folding money on the costs.
They are not dusenbergs and no matter what you asked for the at the big flea market someone who needed would pay your price. So it's up to you to take the gamble on the purchase and the resale . If you bought them right it really will not matter on the cost, moving etc. no that are not making new originals other than tods new motor and that's a different subject cores have been bought here in bulk for 50 to 75 bucks depending on how complete they were . Good luck on your purchase and send us pictures and block numbers
