This is a What Do You Think Its Worth question

I am not going to take sides on this but I know as a fact that the Ford blocks are VERY repairable by welding them with 304 stainless steel rods.

Stainless has a formula for some chromium (little) and nickel (quite a bit).

The welds stick like they were cast with the block and if the crack went through the main bulkheads machines down with a line bore where you can't even see the location of the weld.

So although the argument of nickel is a "junk" factor, it is noticeably more present in the Ford castings rather then the GM's. The difference in hardness is very measurable with the Brinell test.

The GM's when cracked are generally done at that point. The Ford's CAN be kept ticking with not too much difficulty. The question would be rather how far into the water jackets and liner bore the crack goes and if you can get at its entirety?
