On an LS based engine the BW will flat dust the 76mm P-trim. They really aren't even in the same league.

With the stock 5.3 and e85 I plan to push over 15lbs on it. So im thinking over 800hp
not to the wheels of course but who knows I can always up the boost.

THats what I was thinking to just use the s475 now and sacrafice some low end power but have a huge gain up top. Im just wondering if that the cam will make up the difference on the low end with a big *** turbo over the on3

Keep im mind that one is a 300 dollar turbo and the other is about 800 if im correct.
Will it be mostly street driven?

You will want the 475 if you plan on 800hp.
