It depends on what you can put up with. If you can handle a little chatter, then a McLeod 11" Long or 11" Diaphragm pressure plate with their 600 series disc will work just fine, or a RAM Powergrip HD clutch kit will work fine too. I use RAM & McLeod on all of my engines.
If you want something that drives like a new Mustang or a new Honda, then the McLeod RST is the way to go. 800hp, no chatter, no funny business.
When you start getting up to the clutches that will hold 600hp, they're going to be expensive anyway, so it's only a $200-300 upgrade to go to a twin disc.
Just stay away from brands like Centerforce, Zoom, Spec, etc. Don't let anyone, no matter who they are, tell you that a Centerforce clutch will hold 600hp, or that you only need something like a Ford Racing clutch kit...that's how clutches get smoked.
Package deals are available.....I've got 2 aluminum FE's in my shop as we speak.
