Dave, You sound right on. Small Carbs that run 85-90% efficient is much better than big carbs running 60% efficient. Need steep gears and heavy flywheel. My friend Pete used to run a 50lb. wheel with a 6.17 ring and pinnion and a 3.00 first gear in a Nash 5 speed. Car was 280 cubes in a 57 2 door wagon that weighed about 3400lbs. 10.82 @ about 130mph back in 1979. Carbs were inline (660) center squirters with an Engle roller cam. (G/MP)
