No ACL and less than 400 hp, sell me on a clutch

Well, reading several posts in here ive already learned some clutch dos and don'ts. My clutch experience includes factory style on my Road Runner as a kid, and the McCleod something something behind the small block in my 73 Land Cruiser. That's it. The LandCruiser also has factory hydraulic master/ slave. Ive got no left acl ( again)and was a knee replacement candidate 6 years ago, I'm still gettin around on what I was born with, and been Mountain Biking the last 12 years to keep things lubed. Driving the Toyota around does get to the knee due to load at flexion ( there ain't much leg room and im 6'4").

What's your two cents on a clutch for my 68 Notch?
Variables:
Before I tore this car down, I drove it albeit not for hours on end, in its stock format, that was 6 plus years ago.
Ive ditched the 318 for a fresh '69 340 x head, mopar high rise, Holley 2xpumpr, Doug's Headers and a fresh 4spd. Im guessing im in the 360 to 370 HP range. Ive not selected gears yet. Car is for street and fun, no track plans. Rebuilding the pedal assembly was one of the first small parts jobs I did, see pics. Raw external steel parts are clear coated including spring. This was my first exposure to an over center spring, a pretty cool little piece of engineering, and not a cake walk to get on and off! I'd like to leave the spring on/ alone. What's a decent 3 finger clutch? What are the main advantages/ disadvantages of finger vs diaphragm types?
Thanks!
