402 ci magnum into a dart. oil pan sits low

with my dad who was a viper and prowler technician. Ase gold certified chrysler tech for 20+ years installed the 402ci magnum stroker crate motor into a 73 dart swinger slant 6 we still have s6 k member. The motor has a center hump 8qt oil pan and it sits dangerously low so my dad welded a piece of steel to the k member so it won't rip my oil pan off. My dad has passed and over the years accidently hitting pot holes or spped bumps to fast has bent the brace/guard back and I recently hit
a dip in road and hit my oil pan for some reason now I'm nervous. What are my options. Is there a different oil pan?
