McCulloch supercharged Kurtis-Nash 500

McCulloch Performance

Cars are sold on performance, as well as looks, and this is as true nowadays as it was during the fifties. The McCulloch supercharger was heavily marketed to improve performance, consequently much of the advertising featured performance figures, although, as with today, the advertised figures should be taken with a pinch of salt. Many of the advertised McCulloch figures were gained using indicated speed on the vehicles speedometer in conjunction with a hand held stopwatch, giving very optimistic results (i.e. 7 second 0-60mph 1955 Cadillac Series 62). I have collated these figures, along with the more accurate road test figures from the magazines of the day, and reproduced them, as we all like to know what our vehicles are theoretically capable of. Ford vehicles feature heavily again Im afraid, as most of my data seems to relate to Fords.
