For me, changing main caps is too expensive to put in a stock block. If stock main caps won't hold it I want an aftermarket block.
Bingo. I use to spend as little as possible on my 8 and 9 second builds and when they cracked they cracked. 275 passes was the least amount I ever got running those times. Now with my mega block and Keith Black block I can lean on them a little harder. The amount of money it cost to girdle and line bore an engine is what I refer to as " stupid money". I never had a block leak water, oil, or break any other parts and the cracks were found on Winter maintenance.
