Thanks! I recently aquired a 70 V code RR project build date of oct 8 69 missing the original drivetrain & replaced with a later 70 HP 440 so I am trying to figure out what date codes I need to look for to be as correct as possible. I also came up with a 70 V code Cuda project build date of nov 5 69 that came with what I was told was the original block. The partial vin is on the block & it was assembled on 11 4 but I was concerned it might not be correct as it was cast in may 69, until I saw your casting date. So maybe it is correct?
