Is this a good engine for the price

Assuming it's all useable and just needs a freshen up, you can't buy the parts for that money.

The heads, rockers and intake are $2500.00 alone.

Not sure about the block but 4 bolt caps on a passenger car block is not cool. Even if they use a 5/16 outer bolt. I've converted at least a dozen T/A and X blocks to 4 bolt caps but never a passenger car block. The main webs are too thin.
You think even with the replacement block the four bolt is an issue I've read that it's better suited to four bolt mains and if so would a girdle be the way to go?
