And the benifit of a cold weather block is????
What happens if the infamous 230 block has core shift ?
A good block is a block that has thick consistent cylinder wall thickness. I really could care less what year or what the casting number is.
Sadly, I have not heard of any true cold weather block having thick bores. There has always been a few cylinders that were thin. I have one myself but have not yet sonic checked it. But only heard of about 4 being Sonic checked because they are rare.
Hope mines a exception. Do love the thick crank journals though. A standard 400 journal is about twice the size of a 440,s The 230 infamous blocks journal is about twice the size of a 400,s journals. Don't know why that is if they didn't bother to make the bores thicker. Mines probably thin too.
