1971 dodge dart 400 big block QUESTIONS

Ok will do. I just thought of another question. So I am keeping the slant six K frame and I am going to use the S6 to B/RB motor mounts. Would I have to get a special oil pan? Or can notch the K frame? Or dent the stock pan a little bit to clear the K Frame? There will be plenty more questions as I think of them.

Thank you guys (or girls, not sure haha)!!!
