Well im looking to put more power into my 2000 Xtreme, 4.3L manual. Im weighing the options of supercharger or an LT1. I know how much the LT1 costs and the supercharger costs so much less. But does a supercharged 4.3 even come anywhere close to the LT1 speed wise. And if not if not then can a few upgrades be made to a supercharging to hang with the LT1. Any info would be greatly appreciated.
