yes, one of these fit my 91 nicely.

Intake, heads, cam, headers, rear gears or do an LS swap. All depends on how deep your pockets are.

1991 is such a unique year (in my opinion). The latest styling queues, but with the traditional (and infinitely modifiable) small block! I sold my 91', but I miss that car! So many possibilities ranging from bolt-ons to big-cubic inch aftermarket blocks.
I'm not knocking the LS motor, it's an incredibly capable platform, with tons of aftermarket support. It also has some interesting architectural improvements, heads, and the alloy block (not all are alloy BTW).
"Can an LS swap be done on a budget"? Yes, especially when using an iron block and 4L60 transmission. But, realistically it's not for the armature and it will involve some creativity to integrate full functionality of the donor engine and c4 corvette electrical components. I wish someone would make a drop-in (with harness) kit already?
Anyway, "TPIS" is a nice vendor to visit if you want to get an idea of what is available, and what your small block is capable of.

I put nitrous on mine and had a blast with it. Lots of people who have never run nitrous will tell you how bad it is. Nitrous is no different than boost, too much is too much. A 150 shot took my 14 second car easily into the 12's. I think nitrous is pretty cool, BUT, if money was not in the equation, I would put a blower or turbo on the car. I messed around for a long time with the long tube runner system. For the power I was looking for, you would need to do heads, cam, intake, exhaust, and it adds up quickly. Good luck with your quest for power in a time when 1000hp cars almost seem common. LOL

People will tell you the cost of the refills will eventually add-up. Don't kid yourself, superchargers will need maintenance too (belts, possible rebuild, etc.).
