so your switching from a Rouch/tvs1900 to a Vortech SC? Imo get a smaller pulley for the Rouch and be done with it or switch to a actually TVS unit. Personally I would keep my charger I already have, and ditch that 5.3 liter engine. Again, I think I told you before, if you want more get a TVS2300 and put it on a 408/6.7 liter engine. You can always do over 1000hp with a turbo or similar if done right.

IMO you will be dissapointed if you choose that vortech sc. Not really worth that price. You can build a 408 for that price or less. Then add the tiny 1900 on it, for big numbers, its a guy who did that. When you upgrade get the 2300 TVS. Its the most efficient supercharger and complete kits, trust me. Get the 408 with a SC cam, the right one, dyno and street tuned with the supercharger. Then post back your results and videos what a real engine can do.
