Well I'm a little confused. I'm not too familiar with the GT-40 Crate motor but after reading the specs from Ford Racing the only difference between it and the 93 Cobra motor seem to be that the crate has aluminum vs. cast heads on the Cobra. Yet the crate motor is rated between 315-345 HP while the car is 235. What is the difference?
