Not sure of any companies that make a kit, but that doesnt mean that you can't fab one up.
Theres a guy over on the corral that mounted a SC thunderchicken blower on the passenger side of his 5.0L and custom made the inlet and outlet tubing.
I'll try to find more info on it later today, and find where I saved the pictures as well.
BUT I really think it would be a lot less of a headache to just go with the Novi, especially if you can find a used one. I've seen used ones go for around $1200 for the comlpete kit. Not to shabby for an awesome "entry level" blower. check out
