With all the talk of raising Tarrifs, I did an inventory of blocks and cranks. What I don't have is any extra rod sets. I thought about buying the 440Source I beams for $249 a set, just in case, somewhere down the line, I decide to do a mild build of a stockish 440. Anyone have any experience with these rods, they seem to be a much better quality than the stockers and have 7/16 cap bolts. Any feedback appreciated.
