Thanks everyone...when you are spending that kind of money, I want to make sure we are making a good educated choice, and that's what this community is all about.
We ended up with a Wegner Motorsports 416 with a Magnuson supercharger
looks like 850+ HP! and lots of street manners. Carl Wegner is a great guy and knows a few things about LS engines. This is going to be a fun project.
Thanks again- Chris
