273 or NOT 273?

Back when I raced pavement oval track, the chevy guys complained about my 360 so much, I contemplated building a 273, just to prove a point. But we had a minimum idle vacuum rule, and restricted to .420 valve lift. So the 273 just had zero chance. If they would have allowed me more cam, I feel certain I could have still won with the 273, but at 8k-85k plus rpm, rather than the 62-63 hundred I spun the 360
