I'm also considering warranty issues here, I doubt the warranty would stay in force if I tore into it to swap cams. Hopefully the oil pan swap won't be a warranty issue.

I'm pretty sure the best average power will be had with the stock cam.

50MPH!? You live in Canyon Country, right? Anyway, MY daily stretch of the 14 freeway (Mojave-Palmdale) is 75-80 or you're getting run over. The Corvette shows less than 1800 on the tach at 80MPH (and 30+ MPG). The stock LS3 is a real performer anywhere on the tach. some good long tube headers would only enhance that trait. I'd stay with the stock cam for a while and see how you like it.

If you've never driven the LS3, perhaps I could stop by sometime and you can wring the 'Vette out a little. I'd like to see your project anyway. Lemme know.
