Hot Rods Schiefer Pressure Plate Help

Hi all, I have a Scheifer B&B pressure plate that so far is unidentified. It’s 11” and I can hear ***ist rollers when I shake it. Part number on box is 627-0019. Trying to determine if I’m going to need gorilla legs to push in the pedal with this plate. I know Scheifer changed their part numbers around over the years, but this part number seems different from what I have seen in the catalogs. Maybe for a clutchflite? Any insight would be most appreciated.

 

This is a 3000# 3 roller ***isted steel 11" Borg & Beck. For General Motors and Chrysler. Last fall I found a Schiefer 3000# 10 1/2 for my 340 Dart. It is very stiff! I can feel the firewall flexing a little bit. Not something you want to daily drive in the city. If you would decide not to use it, I would be interested in buying it.

 

Had one on an OT Mopar. Very stiff, eventually broke one of the fingers off. Not comfortable on the street.

 

Thanks, yes I figured as much. I can dis***emble and measure the springs and calculate how many springs to pull out to make it livable. Since this is going behind a 500 inch, 11:1, solid cammed, six-pack 440, it’s going to have to be pretty stout!

 

I would leave it as is, and just eat your Wheaties.

 

Yup, good for a stout 440. Leave it as is and head to the gym...

 

@Dan Harris and @lemondana , put a brace and reinforce your firewall to stop that flexing. A body Mopars are known for the firewall cracking and breaking with a good pressure plate. Been there done that and not just me!

I'd talk to some clutch companies and see if they have any that have comparable or even better grip in a diaphragm clutch. Why fight it if something as good or better is available without the h***le? New it's worth some money. If you decide later maybe it isn't something you like it's worth less and you still have to buy a new one.

 

One thing about Schiefer, is it is good quality made in USA stuff. A lot of the big brand name pressure plates now a days are made in China. A few years back, a friend of mine was having major clutch problems, he contacted McLeod and they talked him into buying one of their high dollar dual disc setups. He had nothing but problems with it-they admitted in the end, that some of their stuff is sourced from China. He had a local clutch shop put together a setup that worked. I have complete Schiefer setups in both of my 4 speed cars, a 67 Dodge Coronet with a 440 and a 4 speed and a 68 340 Dart with the 4 speed, both work flawlessly.

 

There may be a way to increase your mechanical advantage so it's not so difficult to press
