Technical Pressure plate dilemma

Will a 11” clutch plate with the three finger style pressure plate etc, (all new) from a 1974 350 SBC fit on a 292 flywheel (from the same years)? I’m swapping out my 350 sbc temporarily to a 292 (From a C10) Which has the 11” diaphragm style and I’m unsure if it’s suitable for this old P3500 breadtruck. Both are using an SM465. But I hear the three finger style is more heavy duty than the diaphragm style clutch pressure plate system... Thanks!

 

There are a lot of if's but yes it should fit, check the spline both should be course(10 if memory serves). The 3 finger could be a heaver clutch but not necessarily it depends on the designed clamping pressure, for normal use either will work the diaphragm type giving easier pedal effort. If you are running say a P3500 overloaded a lot then I would want the heaver duty finger style as the stand up better to heat and abuse(slipping on take off for example).

 

Remember to match the throw out bearing to the pressure plate used.

 

Awesome! I’m gonna go ahead and swap them then. Thanks for the tip!
