273 or NOT 273?

I honestly don't care much on streetability. I have 4.56 gears with a 27 inch tire. My current 340 doesn't make power until around 3k. I'm not looking to run 10's , just was curious If a hot low 12 second street car was possible. After hearing the adversity , I'm most likely going to just build another 340 ( I have a virgin bore block)
Smart guy. Although I would like to see someone build a legit 350+ horse 273, It can be done so easily with a larger engine.
