Two things.
Running 351w that's supposed to be good for 435#/ft tq. Didn't want to develop Corvette truck clutchitis in my left leg, or break any seat mounting bolts stuck in traffic with this due to high pedal effort.
Used the Centerforce 10 1/2" single disk clutch & PP that fits late 5.0's and 351W's using 157 tooth flywneels. Had 3 locating pins, and 6, 5/16 bolts supplied with clutch. Can't see any need for dual disks unless you're at the track every weekend with it. Expect service life on this to be 30k - 50k miles. Grabs smooth, and no slippage.
The CR (and my guess is several others) uses '78 Mustang 302 clutch linkage cable and firewall mount setup. This seemed to be the weak link in the system. Absolute junk!
Late Mustangs use a Nautilus Machine type cam to pull the cable, a heavier teflon coated cable, a firewall adjuster which provides a stronger firewall mount, and clutch adjustment at the firewall, and an adjustment at the clutch fork end of the cable as well. Summit (among others) sell a BBK version of this that I grafted onto the Cobra. Have shots of the conversion if anyone's interested.
Anyway, clutch can be depressed by hand it's so light.
