Motor mounts are correct, i actually had to use 2 1/8 inch shims under the k frame to get the oil pan away from the steering cross link so it would not rub the ooil pan when turning. I tried removing the to see what i might gain, only 1 half a degree. Car came with 273----a terd so i put a 360 in. Maybe a different oil pan and rework the motor mounts to get to 0.
