oil pan question

[d-rock]

are the small block oil pans interchangeable? I just acuired a 73 roadrunner. It has a 318 3 speed. I plan on building a 360 magnum and sticking a 4 speed in it. Would the pan from my 318 work on the 360 magnum?

no the mains are bigger on the 360 so the rear main end of the pan are different size (radius)
