Clutch q&a

[gtwo]

So my 5.4 started overpowering my stock clutch today. Its a 1999 gt with a 2v 5.4.
First question is more just reassurance for what I found, my car has a 10.5 diameter 26 spline clutch,correct?
Second, what "stage" would you recommend for a 400hp max on spray(someday)?
Got good legs so don't care about stiffness, price on the other hand...that's an issue.

I got an autoparts house 03/04 cobra replacement. Holds up well to dragradials....

So the 03/04 clutch is the same?
Do I have to replace the pressure plate as well or is just the disk ok?

Gotta buy a headchange kit at the same time so I'm trying to be cheap.
