The engines are not that drastically different from each other and many, many people have already replaced the components, mainly the pistons, in the LT1 C7's. The article isn't even about the engines, it's to show the limitations of a smaller SC. If you're trying to decide between purchasing a SC today, why anyone in their right mind would buy one with the lowest ceiling is beyond me. The Vengeance guys are throwing darts at a dart board with E85, I know, I get it. But the point is to not limit yourself and plan your mods correctly.

If I had purchased the LT4 instead of the Magnuson I'd be at the same place I am now. I agree with that. But this winter, when I do a custom cam, my fuel system, pistons, rods, etc....then what? It would've been an expensive mistake if I chose the LT4.

I really did laugh when I read your post. Love the "GM shits gold bullion comment" I'm not saying they don't make any mistakes but I 'm a big fan of what they are doing.

I'm with you, if you ever plan on putting in a custom forged bottom end and if you plan on chasing the horsepower numbers you can go farther with a 2.3 than a 1.7 but I think there are probably 3 guys out there running a bolt on supercharger kit on a stock block for every 1 that goes for a custom built shortblock. You just need to know what the long term plans are going into the build.

I still think if you know gong into your build that you are going to build a forged bottom end that you should run turbos. They just have a lot more power potential than superchargers. Somewhere in the middle is a build with some sanity and I kind of think it is the stock LT1 motor with the LT4 supercharger. But hey its just my opinion, I tend to get a little crazy most of the time.
