early a body /6 to 440?

what iam running into is the idler arm side of the v8 centerlink is hitting the oil pan,,,when turning to the right,,,but turning left it doesnt hit...i have different oil pans but they are the same depth at the rear as the one i have...cannot raise the engine any higher

What oil pan do you have? The C body pans will fit. One number is 187. That's what's on my 400.
