Whipples are very reliable--as well as Magnachargers. Whipple does not currently make a plug-n-play application for the L19 454. Neither does the Magnacharger. Vortech makes one for the 5.7L 350, but not the 7.4L 454. S/C the 100k 454 is not out of the question, it's just that you will need to slightly freshen it when you slap the S/C on... I would recommend a Manga/Radix. Contact them directly and see what they can do for you...
