what you might want to do... scavage... you may be able to cobble together a Callaway type setup.
HOWEVER!!!!! And this is important, a stock L98 will not last long under the stress of forced induction.
You might check ebay for a used blower... check the salvagers, too.

All of the supercharger/turbo guys are there.
I am pretty sure procharger has something for your C4

Research it carefully. I had an ATI procharger set up and hated it. The con's outweighed the pro's, in my opinion. Removed it and sold it to a friend. He loved it for all the reasons I did not. When the supercharger let go, it hurt his new motor. Most may disagree, but I have been there, done it, had the shirt and moved on.

He liked the wow factor when you put up the hood.
I hated the fact that engine bay was cluttered up. Maintenance was tough with all the extra stuff. Blower smacked the hood under accelleration.
Made a ton of extra heat. More than you would think.
Boost took nearly forever to build up. Maybe that is an exageration, but centrifical blowers need time to "spool up" Boost is not instant like a roots type blower.
FMU pounds the injecters with double the fuel pressure under boost to get the fuel needed.
Belt driven blowers sap alot of power to turn. Make the car feel like the ac is on when not in boost.

those sound like pretty good reasons. let me ask you something else then: the reason i started researching turbos/supers is b/c it doesnt seem right that the bhp on that car is so low (if i remember correctly, its 186hp), but there also doesnt seem to be much i can find that increases that reliably.
i keep hearing from people who know cars (but not vettes specifically) that that number sounds extremely low and might have something to do with really poorly designed emmissions controls, and that taking certain parts off the car should fix the hp problem, but i cant find any info on that either. so heres the question: what, other than a turbo/super, can be done to make a c4 perform better?

Not too familiar with your year but here are some links below to get you thinking. Hope they don't mind me posting them. And then theres always the easy route and my personal favorite so far... add nitrous

There is a company looking for an early C4 to install and test a turbo kit on. I think they are doing it labor free. Can't remember the site though.

'87 vette - 240 BHP.
Can be made to operate well with ProCharger package. With FI, a relatively mild motor can be run with much more radical NA motors. Peruse the FI/N2O forum and you should see lots of info that applies.
Pete's comments on the early style ProChargers may be very close to accurate with regard to the 102Db level. But, not all blowers have the straight cut gears that cause that level of noise. I run a ProCharger on mine that you can not hear at idle, or any other time over the noise of the motor.
See "My Corvette Photos" for pics of an install on an '87.

I admit that I am one of the rare few that did not like mine. Most are pleased. Have a good look in the Supercharger section of c-4 forum. Lots of good info in there. I am not trying to discourage you from buying one. Just remember any major mod requires compromise. No such thing as free power. FWIW, I am a Nitrous fan though. Most people are not

Have you ever thought about a head/cam/header package, and in your case with the L98, a different intake as well? There's something to be said about an all motor car that is done right that can put down some good numbers.
