How much to stock rebuild a 360?

In the case of the 1971 AMC 360 I posted on here about, I called to get a price on a rebuilt long block for this guy, first, most couldn't give me a price because of the year, it seems they are hard to find for that year but a late 70's or early 80's was available. the two places that gave me an estimate were with in a few hundred dollars of what it's costing for the machine work and and parts. I'm not really charging the guy but a couple hundred to assemble and install it. And at least I know what was replaced/rebuilt in my engine!
