I'm a NAPA guy.  Their diaphragm style clutch/pressure plate = smooth/EZ pedal and  would hold 350+ HP no problem unless..........you have a tubbed/narrowed  rear with 14+" wide sticky tarz. Then the  T-5 will scatter  next!

Lykin is VERY sharp on another web site so his advice will prolly be "spot on".

I believe the 67 would use a 157 tooth flywheel but after 50 years who knows what can be there? Just make sure the flywheel coming with the 351 matches the bellhousing size. Personally I’d use a stock clutch on the street. For one the less pedal force needed. You’re probably going to loose traction and spin the tires long before you exceed the limit of a stock clutch and it’ll be easier on the thrust bearing.

My old motor in my 66 had a Rockauto close out special, never had any issues with it. My present motor, a GT40P I’m using a King Cobra clutch kit only because is was given to me for free. Works well but requires more pedal effort then what I was hoping for and that’s with a MS roller bearing kit on the pedal hanger and a clutch linkage made with rod ends. I’m almost sorry I didn’t use my old clutch.

I run the King Cobra in my '67.  The pedal effort is quite light IMO.  Of course, pedal effort is like anything else that goes along with how something feels.  A guy used to driving a Honda is going to think any V8 clutch is stiff and vice versa.  Then there's leg strength, etc.  I grew up driving old school cars and trucks with mechanical linkage clutch actuation.  Most things feel light in comparison.
