How much would a AMG 6.3 V8 M156 engine cost, like at a junk yard?
An engine like that would probably cost you close to 10K at a junkyard. Especially since the yard would have hard to pull it out of the wreck and do a lot of labor to make it able for you to buy it. Junkyards will sell to anyone with the money, but I’ll all but guarantee you won’t fine one sitting on a junkyard anywhere.
