i just picked up 2 for $60, one went at an auction for 250. generally a turning over motor would go anywhere from 50-350. A running one with need of rebuild 350-750
a rebuilt one 750-1500, hopped up one depends on how hopped up
It is definitely regional and I see them appear in waves. I've picked a up good runners and the truck with them for $500 and I've seen runners go for more than that by themselves. I've even seen seemingly frozen engines try and go for over $100. Flat 6's are definitely harder to find. I think mostly they get scrapped and no one thinks to try and sell them. I got both my 8 and 6 with the trucks for $500ea. The 8 is a driver and the 6 needs TLC to get it running.
Thanks! Sounds promising. I'm in NC. Got a big swap meet/flea market coming up right after Labor Day. That might be an opportunity to look for one. The pricing info is helpful. Probably look for a block or one needing a rebuild. Forgive my ignorance but what is EAB, 8RT, etc.
