Most yards just scrap broken block engines, seems even if an ear for the alt or whatever is broke off too. I paid 350 for one with a broke timing chain... 500 for another the crank got snapped off in back from a hard front end hit, but rest was perfect, even block still good. Got all kinds of parts basically for free as the heads sell for good money off newer ones. I buy all the cheap ones I can get for spare parts.
