Can't imagine anyone local is going to want the block and doubt there is interest to pay a significant amount to ship a it. I'm not looking for any real money for any of this either, but I doubt that will change anything.
The yellow engine with the blue oil pan has me really baffled. I wonder if someone "spruced" it up while it was in the car or something. Hard to tell, you have to look close to see the yellow so not certain there isn't yellow on the pan, too. Didn't seem like it, but I wasn't really look for it either. And the back of the block is yellow, too. Seems like it would be hard to get that painted in the car.
