The TT series are affordable converters while the SC series are machined from a chunk of steel billet and are designed to stall behind the huge torque a SuperCharger will produce. A TT3000 would probably stall to 4000 behind my engine
If your 4.8 is stock and running around 6 psi of boost the TT3000 should work for you. If you plan to increase power in the future I'd say get the SC series. I don't know much about the Vigilante but have heard nothing but good things about them.
A friend of mine has a '00 GMC ECSB with 6.0L with STS Kit. It is all stock with the exception of camshaft and different pistons. He is running a TT2600 and it works well for him although he does wish he went with the 3000 instead.
