Jim and Brian are on to something. You could also use less stall, maybe 6,000 but get the "tight" 3" converter and use a 8.10 gear ratio with a 12" tall tire.
Seriously though, remember the COPO clone '69 Camaro in Hot Rod a few months ago? It was specifically built for the FAST class and it ran mid-low 11's on bias tires and exhaust manifolds. I recall it had lot's of cam (.700+ lift, 270' ish duration) and lot's of cubes and compression. Even considering the stock exhaust manifolds, it would not surprise me if the Camaro was shifting at 7,000+ RPM. These guys are basically building comp motors and making them look stock.
Mike Noun did a similar thing with his '69 Firebird with the exception of headers and aftermarket heads. His car would not meet the rules but it did look pretty much stock. He ran 11.70's on M&H tires. I believe his shift points with the 455 in this configuration were 5,800 RPM.
