BEST ET on stock bottom/a4/rear?

I'm just curious as to the best ET anyone has seen with a stock bottom end car ( LT1 only) with stock a4, stock converter, and stock 10 bolt? Nitrous or another power adder ok.

I'm running 12.2 on a stock motor + 150 shot, but I'm about to add LE 2.02 heads and cc 306. Llyod said I should be in the low 11's with this combo.

Time in sig... cam a little bigger then a 306. No nitrous... stock TB untuned spinning off the line... there's more in it... new times if I can ever get the POS fixed and running
