833 B to 833OD

moper
I run a factory 340 clutch disc, right from MOPAR. They don't last that long (I mighta changed 3 of them plus a teener disc in 100,000 miles) behind my 366, but they are easy on parts,(especially that teensy O/D gear), are easy to modulate, and are easy on the pressure plate as well .The spring pockets give up, long before the friction material goes. When a spring pops out it vibrates, and then I schedule a replacement disc install. ( The teener discs aren't worth the install). Changing a disc is only about an hours work for me.
I run a Centerforce diaphragm pressure plate. Excellent piece. For street use I shim the plate away from the flywheel about .030 to .040. This makes it a kind of slipper clutch off idle, and let's me practically dump the clutch at 850 rpm with 3.55s and I power away. Modulation and driveaway is easy,and the disc lasts a bit longer, and then at higher R's the flyweights put the clamp on.Since I have been running thus, I have not broken anymore parts.
The Centerforce II is an excellent track piece, able to easily handle my street engine( at one time with the 292/509cam).
With the II disc, on the street and no shimmage, it would easily bark the tires on the 2-3 shift at moderate throttle, and often also dropping into 3rd at 4400 rpm under full throttle, which is 70plus mph, and with 295s.It broke a lot of U-joints and stuff. I pulled it.
So that piece transmits.
I run street-use only.
