273, the good points

I used the solid Isky 1012-C in my 1965 273 Bracket racer. It pulled strong thru the 6400 RPM trap speed, was always afraid to spin it any faster. Specs are advertised 312 duration and .580 lift. (idle speed at 1200 rpm sounded like a top fueler) Based on ET and MPH it was pumping around 310 horsepower.
