AndyF,

I went with the 440Source ultra light crank and their 7.1 rods. My Ross pistons came in around 524G's. I was hoping the light weight would be easier on the stock block. So far, I am unable to detect any signs of walking. Which main caps are you going to use?

Do you think the lighter reciprocating weight reduces the stock blocks susceptibility to cap walk?
