Roots Blower on an LT1
Here's something I found on one of the other sites, maybe you guys will find it interesting too. It says for sale on the top of the page $1800
Custom setup looks pretty cool.

Definitely have never seen one of those before! I always wondered why there wasn't a roots setup for the LT1's and now I can see why - their target audience (F-Body's) would have to do a lot of modification to get that system to fit.

I'd love to have a Magnacharger on my C4.

Magnacharger does make a SBC version. But not anything for the LT1. It appears that this guy did a fair job at building a intake to adapt the Lightning blower to it. However it won't fit our C4s but as with anything a little ingenuity goes a long way. Just goes to show you that it can be done.

You could mount it like a Vortec, and then pipe it over.
Kinda like a Blower Bentley.
You'd get a flatter boost curve with a roots, more boost at mid range.
BTW front mounted roots blowers where how some of the original dragsters mounted them.

Ok that blower setup is insane and exactly what I would have done. The pipe from the throtle body is a easy build at a machine shop - I myself have done a similar fab for an entirely different project at Texas A&M's department of Physics metal shop (shhh no one noticed me after work making stuff) I know with a little planning all that stuff can be fabbed to fit. I just dig this guy's tenaciaty in getting it done. Even making the intake and throtle body ram could be done by phelonic materials. Ok, im thinking out loud. That design got me wondering what I can cook up for my 86. I guess the most limiting factor would be where to get a cheap blower from. ok it would proabably make more sense just to buy it from the guy. I'd hack on my hood for braggin rights on that!

This in Magnacharger's old supercharger setup for the SB chevy, non-LT1/4, though you could get it to work on an LT1/4 if you relocated the injectors. And I have seen it mounted on a C4 Corvette, as a matter of fact there used to be a kit. Since the blowers take the air/fuel in from the sides it fit under the stock hood. 
It's basically two roots blowers angled at each other.

How much displacment does the M112 push out per revolution? Also how fast can it be spun, 1 crank rev = 2 supercharger revs? Definately some DIY fabbing, either milling it or doing that old fashion way with a grinder and cut off wheel.
