Big block duster pain in the A$$

Well i have two 187 pans and a 699 pan and mine wont clear, so if the indent isnt any larger on the 440 source pan that wont work either. Still need to dimple my 187 pan

Then you have the early center link with no drop or the engine sitting a bit low..... My bet would be center link as I can set the oil filter on the K frame before I have pan issues.
