I did not, was just making the point. That is a good way to possibly identify the Indy block as well as others but I have seen a World block or two that exhibit some of the casting irregularities that production blocks do. Meaning some core shift, so that may not be the best way to tell on all blocks. I have one here that is higher on the casting that is a STD cam location block. I believe he is looking for way to quickly identify them apart and not sure without measuring I would be confident if the seller was unsure or you wanted to verify it.

I think everyone might be getting a tad sensitive around here. Must be your long winter. If it helps it is supposed to be 80 here today
