I'm going to compare it to a 402 pan that I have that works on 66-70. If there is doubt, I will have to buy a pan and pickup to go back to stock. I have plenty of different pans and pickups, but no spare 1/2" pickups for a stock application. Also I have a 66-67 Hemi K frame that was modified to work with a 70 type sway bar. If everything gets ready to install in a car before I have the right combination, I can always use the deep pan and pickup that was on the engine.
