[classical glass]

Hi guys, i'm looking at a Contemporary Cobra and while checking out the motor I can't seem to locate the casting info on the front right side of the block. I'm positive it's a side oiler and everything else checks out ok receipts for engine work etc.. I got right down into looking at the block and I can't find anything. The block hasn't been sanded or ground down to remove anything, I can't seem to get a handle on this. Anyone have any ideas? Am I looking in the correct area? Thanks in advance.
PS The heads have C5AE-F Casted on the heads that tells me it's a 1965-66 date.
