Just the luck of the draw on a stock block, because you are NOT going to "fix" it, because it can't be fixed. Stock blocks are weak in the main webs and that will never change. Doesn't matter who has done what or how long so and so's lasted. Just is what it is.

Somebody said sleeve it and run it........well you could do that, but eventually what you will "run" is the crank over..........LOL!!!

When I have used alum caps, I prefer the standard two bolt type with no girdle. Many will argue the point, but I think the girdle does more harm than good.
