Is this a Good Deal for a ready to go Block?

No here also...

I can have it done here in Nor Cal just a bit cheaper than that, too...including decking with a plate.

Finish honed without pistons? No thanks.
A late 360 at .060 over? NO! Not unless he's willing to sonic check it and YOU can see the results...
Decked without mocking up the crank/rods/pistons? No thanks.

If you need caps for a block, check the ads or the junkyard. ANY late SB block even with it's complete OEM caps should be align honed anyway.
