I had a .040 360 block that was rebuilt and had a wrist pin failure, too.
Just yesterday it left on the scrap truck, it had a deep groove in #5 and would not clean at .060. It was a 1977 block and might have been savable if it were an early block. I bought a set of 273 rods that have been bushed for floating pins from a Moparts member. I plan to use those in my 1990 roller block when I get around to machining it, it had standard bore pistons in it and almost no ridge. I will need some very light pistons to go with this build and would like to see 9 to 1 compression and maybe a 4" crank.
