273 or NOT 273?
The chart needs a tune up. The 273-2 barrel was rated at 180 not 190. There is no specs for the 273-4 barrel which was rated at 235 horse and 260 lb/ft of torque. Now look at the 318, 5 horse less than the 273-4 but 340 lb/ft instead of 260 for the 273. (and at a lower rpm with the 318)
