John,
What Ernie is telling you is so true. If you undercam it, cruising on the freeway with a WR 4-speed and 3.31diff ratio is noticeable like the engine is straining to rev. If you overcam it, and say the power is in the upper 3k range, it will feel like you need lower rear diff gears to keep it in its sweet spot. Many people have done the WR Toploader with 3.31s and its sort of an agreed standard when running the 428s especially.

I bascially have the same heads/trans/diff ratio as you. I've tried the 282s, 300s, a 295s-custom grind I have now, and friends with the 270h and new 286h cams. If you want to do a solid cam and not so radical, the 282s is a nice all around cam. I had this in my last car and it was great. If you want to go with a bit more rumpity rump and higher rpm performance some people like the 294s cam like Ernie was talking about. I did a custom grind just a tad more lift/dur than the 294s. I prefer it because I wanted it tad more radical. I don't know, if I had to do it over again, I'd probably drop back down to something like the 286H, but in a solid cam; custom made. I think Comp came out with this one so it would be right between the other two, but I don't think they make it in a solid grind yet. You could copy it and do a custom grind cam like I did from Crower. In my case I took two cams and compared with software on three different 3 mile track scenarios for reference and split the difference on a few parameters. So far so good. Like he said, matching it all up is the trick and including spot-on carb tuning. Once you get it dialed right in, it makes it that much more fun to drive in varying conditions.

To me, cam selection and drivetrain setup really comes down to how you plan to drive the car 80% or more of the time.
