Oil Pan Schematics
A 402 is the shortest
without a notch over the c-link and it uses a straight pick up tube. Mine barely scrapes the 402. I do have a torque strap. However, it will be very tight at the driver side K at the lip joint and the bucket corner though. I cleared the lip on my K years ago.
