I was around a few of them. In stock form, they had good bottom end torque, but weren't very reliable if routinely wound up to high RPM. Had a buddy with a Mid 70's Grand Prix that liked to wind them up. Went through 4 engines in one year. One of them only lasted 28 days. Kind of a "Crowbar in a sandpile" situation. Patrick
