Once you get up around 500hp, its time to upgrade to a better clutch. The only thing better than a DFX is a multi plate clutch. I don't think you can get any better on a single plate clutch than the DFX.
I've got that same set up in my Cobra right now. I'm making 638rwhp and the clutch is holding nicely. I've raced the car, driven the Cobra in the city and on the interstate and the clutch performs perfectly.
Just my opinion, keep the stock flywheel. Its aluminum and a very nice unit. Go with ARP hardware for the install !
The input shaft is very easy to install, you'll need some RTV sealant.
The DFX clutch did require a fair amount of effort to break in. Much more when compared to a stock type clutch. I've got about 12K miles on the DFX clutch and everything is "peachy keen". I highly suggest purchasing a fiore clutch adjuster.
