What To Do with a 340 engine?

You need to have block and heads magnaflux for cracks, that way you can get more money, As B'cuda posted ,basically could be scrap to another buyer, REASON i know, 2 months ago ,drove 400 mile picked up used motor for my duster, When i took out crank , it was bad, had wobbled inside block , had 2 cracks at main bearing, couldn't see by eye, just happy the shop i took it to ,for boring .030, magnafluxed block and found cracks, so while i was upset at the crack, i'm just glad it was caught before machining and assembly and all the work to put it in the car.
