Good Clutch?
I am about to convert my 72 from auto to manual. I have a freshly rebuilt M20 wide ratio that I'm going to install. I have a stock 200HP 350 NOM. I do plan on cam, and top end kit at some point to wake the car up some.
Any recommendations for a good clutch assembly? In my old 73 I used a Perfection clutch from the local Advancedauto, but it seemed to be "sluggish" even on a stock motor.
Thanks

I used the Centerforce DF because I needed the clamping force behind my big block, BUT I wanted a street clutch feel so the wife would be comfortable on the occasions she wants to drive. I've not been disappointed with its performance. I don't really consider it a racing clutch if that is what gcusmano74 is referring to. The ceramic puck clutch I removed was a racing clutch. The Centerforce II is a good choice also. It uses the same pressure plate but a slightly less aggressive disk.

I had the centerforce and always had some vibration, pulled the transmission out you could see the weights that sling out at higher RPMs were not centered. I removed the weights and now its smooth as silk, I would not buy centerforce.

I have been running a CF II for several years, without problems, on my 383 stroker. I would estimate flywheel HP and torque in the 400 range. Gotta get it on a chassis dyno this year.
It is a strictly street driven car. I do, on occasion, do hard launches without any problems. I researched the CF line before I purchased, and the CF II seemed the way to go.
I wonder how many people really need a CF Dual friction clutch, based upon what they actually have for an engine, or is it just bragging rights or every weekend racing?
Curious as to what the CF Dual people have for engines. Dyno results are needed to evaluate your combination along with vehicle usage, drag racing, etc. I will not speculate on my actual HP and torque until after a dyno test.
My modifications are in my profile. Using those specs, is how I came up with my WAG number of 400 range of engine HP and torque.
Feel free to disagree/dispute my WAG numbers while you supply your own WAG numbers.

I have a couple of Centerforce clutches. They perform well and the pedal feel is just like stock. I don't really beat on them though. Just some spirited street driving. fI've found the generic replacements are a crap shoot, so now I go with Centerforce every time I need a clutch because I can count on them to work the way they are supposed to.

LUK clutch is great they wont handle to many 5000 rpm clutch dumps but grab tight when you need it to with manual linkage my pedal is a bit stiff so if you want something easier just swap over to a hydraulic clutch setup

Thanks for all the input
I went ahead and went with the NAPA clutch and flywheel. I have always had success with their starters, alternators etc. unlike the cheap stuff from Advanced/autozone, and if something is wrong I can put my hands on somebody close by
