Stout Yet Streetable Clutch Choice

[pwtjr]

Trying to make the best decision on a CLUTCH for my 69 Superbee. I have done the usual and Googled the subject. Also searched various forums. Alot of good information out there for sure, but was wanting to get some Mopar specific up to date opinions from the crowd on here.

My setup is pretty common: Mid 500 horse 440 with hydraulic roller cam, CNC'ed aluminum heads, 3 inch TTI exhaust, 3:55 gears... you get the picture. The cam is Comp's off the shelf 286HR, with duration of 236/242 @.050. Compression ratio is figured at 10.8:1. I am hoping for a really nice torque curve to make this heavy old B-Body alot of fun to drive around on the street, and hit the dragstrip 3 or 4 times a year.

My transmission is the 23 spline unit. I went through the transmission, and am now in the process of deciding which clutch to put in my car. With the internet research I have done, I have 3 options in mind:

1. McCleod SuperStreet Pro - dual compound type disc with diaphragm plate
2. McCleod RST - Twin Disc organic with diaphragm plate
3. SPEC Stage 3+ - single disc carbon metallic with diaphragm plate

Anyone have a similar setup using any of these options? The info I have read on the SPEC clutch is making me want to try their stage 3+ but haven't heard of anyone using their stuff. Obviously McCLeod has a great reputation and I couldn't go wrong choosing one of their products.
My car will be driven 2-3 thousand miles per year. I realize the street manners of the real good sticky clutches require some getting used to. I am okay with that. I want my cake and eat it too, but understand I have to be realistic.

Any comments/help is appreciated.

I love my Centerforce Dual Friction. Did you look at them? Centerforce has several options to consider,,,,,,,,,,,,,,,,,,,,,MO

Got lucky, got an over the counter parts store clutch 60k pounding miles ago. Has a lot to do with the driver.

I ran the McLeod Dual Disc Street Twin. Smooth as silk and easy pedal pressure. The '71 Road Runner was putting out 554 Rear Wheel HP.

I ran a spec 3+ I'm my dart for a bit. First go around It slipped. (I don't think it was right) Sent it back and they redid it for free. When it came back it had a stiffer pedal and grabbed real hard.

Hard to beat a cf dual friction though for a mild street stop car.

Spec clutches are crap on pretty much every application.

my choice are the twin plate clutches.

Another fan of the Centerforce Dual Friction clutch set. Great holding power and easy on your left leg.

Did you use the RST with organic plates or the RXT with metallic/ceramic plates?

Hold it, we got a problem here..............when I go home tonight I'll look at the box if'n I still have it.

Yep, here it is, the old McLeod part numbe,r 64426B-00-02 the Long style.

I have the centerforce dual friction as well and love it. I bolt on slicks and go to the track with no issues with the clutch.

Sounds like a lot of fans of the Centerforce dual friction.

Yup center force dual friction here too, great clutch.

When, my Centerforce dual friction was new, I had to slip the clutch quite a bit in loading the car on a trailer..3-4 times. I have adjusted the linkage recently and wondering if what I did will affect the clutch? ....................................MO

I can definitely relate, I did the same thing a few years back, on the way to the dragstrip, abused the car most the day, then reloaded it on the trailer..... bye bye clutch. Tricky getting a four speed big *** B-Body on a trailer.
I use a winch, or just drive my car to the track now days. Fortunate enough to be 20 minutes from my local 1/8 mile track, and an hour drive to Indianapolis. It's always nice to just drive your hot rod into the track, run good, pull out of the track, and pass all the guys you raced with trailers on the way home... windows down, smile on face.

which reminds me... I need to install that line lock on my car that I ordered like 3 years ago

That's the best, had alot of fun doing that with my rr and the 440. Would even hit drive through. Will do the same with the 511 someday when I have time..
