Ok, I'm not dead set on using the .509 cam. I know it's an out dated profile. Let's try this, I know many of you have way more experience than I do when it comes to camming a 440. I'm open to suggestions as to which cam to use and I should say that this is a street engine going to be used in a B-body, auto, factory high stall convertor, with 3.91 gears. I appreciate all your input.
