clutch for my 65 barracuda v-8

There are two ways to hold more torque in a given clutch diameter.

1) Add clamping pressure

2) Use a material with a higher coefficient of friction

A combination of the two may also be used.

An increase in clamping force will increase pedal force. The pedal effort does not have to be huge to get the job done, but it may need to increase some in your setup.

A disc with a better COF may be all you need. I used to run a stock VW pressure plate on a Clutchnet disc - with a 302 Ford crammed in a 914 Porsche.

That is why I said to call them. They are in the clutch business. Lots of choices. I prefer the 6 puck sprung hub disc on a street car. Not everybody does. Call them and get some technical help with your combo.
