There are very few Cobras (as a percentage of Cobras out there) that get into the 11's, VERY few. Most, even with BIG horse power generally run 12.1 or 12.2 at best.

Why is that? It remains somewhat of a mystery to me. Small block or big block, low 12's is reality. The major difference between a SB or BB is the trap speed, not so much the ET.
