Dual supercharged L98 using 6-71s

I'm pretty damned sured I wanna try this. I'm laying there in bed last night, thinking of crazy **** to do, and it pops into my mind...what if one were to get a couple of 6-71 superchargers (rebuilt to street specs), find a good mounting setup (fabrication is easy if one has TWO superchargers putting a fire under his ***), and fabricate a housing for the inlet and outlet of each supercharger, having them machined so they bolt up tight with a gasket. The inlet sides could be plumbed to large cone filters, while the outlets get plumbed to an intercooler, which then obviously, goes through the MAF and to the TB.

I know i can pick up 6-71s on ebay cheap as hell. I could get an appropriate intercooler SOMEWHERE for sure, and exhaust tubing could be bent to plumb all this crap in. I could cut the flanges from flat steel, then weld a "cone-type" shape onto each that runs into the tubing.

The only thing is, I have no idea what the 6-71 puts out. Anyone...anyone? I'd like to keep pressure around 10-12 psi. BOVs are cheap.

I dunno, is this a logical setup? I just think it'd look sweet all polished up and sexy under my hood. Plus, I could say I have a dual-supercharged IROC. I just want to have something original under the hood.

Show piece only. Makes gobs of power, but just not practical. Saw one on a dyno last summer, pretty impressive. It was on a 455 old going into a 442.

ATOMonkey, I saw one in a Buick GSX. It was a 455 also. Popular Hotrodding TV did a feature on it.

We were looking for custom exhaust shops and ran across this guy. He was completely redoing his 442 after it won some big show a year before. When I saw it, it was body off in primer. That guy has a lot of time and money to waste.
