converted that is 447 ci. I suspect that is the old 460 cubic inch block kind a thing. Either way back in the day of the old 460 was a good engine, lots of power, I loved it and something can always be said about power. Another saying back then was it passed everything but the gas station and thank god for a extra tank, lol, actually it was 14 miles to an imperial gallon, didn't matter uphill or against the wind. But all trucks were give or take close to the same, that was in 1975.
