So what about 64 valiants, does it make a difference in that pedals throw. I am running the 10.5 set up with a kevlar disc and 3000lbs pressure plate, three finger style. Would I benefit from reinstalling the the spring or benefit from the longer pedal throw?

I really don't know anything about that year. You would have to figure out the geometry from one to the other meaning years 67 verses 66 and back. I only collected 67 -76 cars and parts or I could compare them. I do know they had a different bell and fork.
