This engine came from a 275 GTB/4 alloy bodied car. The owner wanted a totally stock rebuild. I’m always surprised by the power numbers on these engines. The factory says 300 HP at 8,000 rpm and 231 ft-lbs. of torque at 6,050 rpm, but so far, the engines we have tested are far short of those numbers.
