Well, you need to figure out how you want the car to perform. Are you looking for peak numbers at a high RPM or more power under the curve at lower RPM's. Are emissions an issue? Do you want the car to lope or not lope? Do you plan on putting in a converter?

Vinci over in Orlando has some nice cams for an automatic.

Here, this will help explain a few of the parameters that govern the cam design. Good read if you are not familiar with cams. If you want good low and mid-range power, then you also need to compute your dynamic compression ratio for any of the cams you consider. This is computed using the intake valve closure rather than simply the cylinder volume.

cam

You might look at cams in the high twentys-low thirties, right around 580-610 lift. I think a 3000 stall would be a bit low for the 3:15s, you might look at 3200-3600. Good luck with whatever you choose.
