Quote: The 535 rod is the stock 413/440 rod that is 6.768" C-to-C. What undersize are your rod bearings? To increase stroke by offset grinding you have to end up with a smaller rod journal. Unless you are running 0.040" undersize rod bearings I doubt the stroke differs from the standard 3.750. I think there are a lot of measurement errors that are confusing you.

It is possible for the stroke to be off by that much , the crank in my 383 is 3.370 when it should be 3.375, it is cut .010 under so I don't know who shortened it, the factory or ? The plus side is my pistons ended up at zero deck instead of poking out of the block.
