Rich will make it pop too because you are blowing carbon off of the plugs from a rich mixture. That is probably what happened to your power valve. They are very sensitive to any kind of a back fire.

As far as the Centerforce goes, if it is the dual friction, it really isn't crappy, just a little strange. I've had three of them in three different cars. The Taurus SHO ate it up in 8,000 miles.

Have a Chevy 11inch in my 68 GT350 and it hooks up really nice.

The Pantera has one too and is the Pantera dedicated 10.5" unit.

Not that I am an expert on anything but I can tell you that, yes, they sure do need to break in and yup, fresh out of the box you can make them slip with not much problem at all.

There is an old adage about breaking in an ENGINE the way you want to use it. This just ain't so with this Dual friction unit. You want to drive it normally, if not even baby it for a couple of hundred miles.

I'll bet you a nickle that if you pull this thing apart right now, not that you're gonna', you will see the nice little (about the size of a quarter) hot spots you just put on the flywheel?

Patience there bunkie. The damn things do work if you give them half a chance but like I said, they are just a little unique as far as a break in procedure.
