I've got a stripped engine block that is either a 427 or 428 cobra jet (it was confirmed by the engine guy from cobra automotive) it has verticals ribbing along the outside of the block which I'm told means that it was a replacement block rather than one installed in a cobra from the factory, I haven't been able to find any stripped blocks for sale to get an idea of what it's worth, I know regular stripped 428 blocks aren't really worth anything, but was told that the cobra jet blocks are different, any ideas on what it's worth?
