Whats it worth 318 fresh bottom end on Craigslist

Just noticed some of the relief cuts(first photo right most 2 cylendrs) are not the same as the others. Is that normal?
I think seller screwed the pooch and is cutting his losses

Thanks Dana67dart
I see what you are saying about the relief cuts not being correct, under tight circumstances that could be a problem. Seller is not the builder., so they dont have any info other than what the photos offer

I found the ad. With those circumstances, I believe you could buy that engine a lot cheaper. Act quick, offer them $1200.00, I think you can buy it for 12-1500.00.

Thanks Roy,
They are asking much less and I realize a lot of the build cost is probably labor and not just parts. Wondering if the sum total of the parts is worth five hundred.
