Nice! I was looking at Blackjacks before I bought mine (the dealer practically threw my 427R at me, so...).

The Blackjack is a great car - trouble is (and I found this out with mine), since it is a limited production car, there are not a lot of mods you can do to it since it will always be worth more untouched. As long as the mods you do are reversible and you keep your original parts, you are good to go.

As for what I would do with the supercharger, smaller pulley, CAI, and a new tune. I would keep all the parts ROUSH brand though, to keep it in the family! Welcome to the Roush crew...

And, for the earlier poster who said his dad didn't buy one because it wasn't practical as a daily driver... tell him my 427R is my daily driver, and I fight the mean streets of LA five days a week in it... so, yes, it's GREAT as a daily driver! 38,000 miles and counting.
