If you aren't tooled up to weld, a novice can plug that crack. I have used tapered plugs on a couple of heads, worked well. "s***ch" them. Drill, plug, drill the next hole so it overlaps into the previous plug a little. Repeat. A word of caution; It's critical to get the feel of the tap. Breaking the tap off can ruin your day. Regis in Dallas Tx sells the plugs and tools to do it. The plugs are cast iron, tapered thread. Use a tapered drill they supply and a tapered tap.

i have welded a lot of blocks and heads. i have even welded up some custom heads for inline 6 chevys. one thing never use br*** if you don't get it right you will never be able to weld it. all that said i would stich it like others have said. have used it on a few blocks. it works great.
weld or not ?get your strait edge ruller and check the deck for straitness,then fill it with two part epoxy.
I found the antique can of Smooth On that I described earlier in this thread. It's for crack repair in Iron. I was on a web site about 7 years ago and when I told them about this they cried BS. Ironically no one did that here!! Anyway,,,Here it is. I can't find a date but it still works really well.
A really low cost way to repair this that would work just fine is to use Marine Tex. Just rough up, possibly drill holes at the ends (not sure they would even be needed), degrease and go to town.
There is an easy fix to that....... buy a Ford! Sorry had to do it. I have not had much experience with freeze cracked blocks, Id have to drive for days just to get somewhere cold enough. Its a US issue, but going off the others it sounds like you can save it. Doc.
They make cast iron plugs. That you drill tap and you drill the next hole at the thread line.Continue to install plugs until you plug the length of the crack.It basicly s***ch the crack wth plugs works great
Dude.........Check out my report I just posted!!!!!Your crack is almost identical to the one I just fixed.........I was able to paint my black the next day! Good Luck!
If the crack is up against the deck you will be hard pressed to keep it from cracking again, two different thickness metals. A good machine shop can s***ch plug it but it will cost more than a 327 block is worth. My 348 cracked in the same place we tried several times to weld it with a proffesional welder, kept cracking, had to replace the block, that was not a cheap deal, later my machinist told me he could have s***ched it. Runs about $100 a inch, in my case with the complicated maching of a 348 it would have been cheaper, that block had about 1500 miles on it.
