May be worth it if you bought the motors already pulled. I dont know what id pay for a whole motor or trans. I know in transmissions that theres quite a bit of brass. The synchros are brass.

As for the alum, Id just focus on stuff easy to clean. Heads, pistons, intakes. I can clean a head in 20 mins. Hack job but hey, its scrap. Most intakes i just take an air hammer to the base of vacuum line ports and they pop out. Blocks may be a challange. Youve got that sleeve inside the cyl. Plus a bunch of other crap.



Sounds like a great idea IF you can get the motors or trans already pulled. Time to pull them would eat up profits. Unless you have a claw that can just rip them out. LOL

Get in contact with shops. I know we have about 8 transmissions waiting to go to the yard. If someone came in offering more per lb than the yard, hey, they'd get em, and get em every time i got em. I dont tear down transmissions. Usually just smash the bellhousing off. But I tear town the blown motors we get if theres no core. Most shops cant be bothered.
