Quote: Up until about three years ago every SS/AH guy used a factory block. Most, if not all, of the new engines use the new World block, but it is still similar to a factory one. When Jim Pancake set the record in 2006 with his Cuda @ 8.55 & 155 it was a stock block. 3210 lbs.
They have the advantage of cross bolted mains though.
The stock block may hold up for awhile, but it will eventually split down the mains and then into the cylinder walls. Ask me how I know.
