Pro-chargers for a 454 TBI?

Ok so i have a 1991 chevy 1 ton that looks really nice. I want some more go...though. Superchargers you need the right set up and i don't really feel like drilling a hole in my cowl hood. Turbos need the right set up as well and alot of fine tuning. But what about pro-chargers thought. Are they good. WIll i have to rebuild my whole engine or can i slap it on and go. It is a throttle body 454 that i am pretty sure is pretty much stock. If you have your foot on the ground it usually shift between 4500 and 5000 RPMs so it might have an RV cam in it or something. I heard pro-chargers give about 60% more horse power but i don't really want to over haul my engine if it is needed. Just tell me a little bit about them. I want to learn so please help me out. Or point me to a website that will give me some more info. Thanks

    For the best TBI superchargers on the market......http://www.tbi-superchargers.com/

    The shift points have nothing to do with your cam.

    If your not happy with the timing of the shifts a good heavy duty shift kit will be your best bet.

    As for having to overhaul your engine,if your bottom end isn't 100% you'll have to take care of it before you can use any power adders.

    You could try the pro charger website. From what I know about these engines you will want a good matching cam and a new set of heads. The factory peanut heads have such small ports and the factory cam is so weak that a supercharger of any type will be fighting an uphill battle and will not do much for you. That is why you need to see what pro charger says.
