Joe, did you change engines AGAIN ? No matter, my clutch comments go back to when I first got our 47, about 14-15 years ago. Had the same-sounding clutch problem. Bottom line, the so-called rebuilt clutch was never right. Too much 'marcel' on the disc, and fingers never adjusted correctly. That clutch eventually wore in, meaning the 'marcel' flattened and the surface wore some, and then it would release properly at about half-to-3/4 pedal travel. Eventually, though, I found a clutch rebuilder that knows his stuff, and got another clutch that works as it should.
Another thing I came to believe, I looked for, and found, ORIGINAL Ford discs, old stock, and probably contain asbestos. In my opinion, they perform better. And, they have the correct 'marcel', right out of the package.
Some of this was learned through discussion with some of our 'club' friends, Dan Krehbiel (sp?), Jon Roberts, Joe Mac, & Bill McGrath.
Side note... I have never liked the way the 10-in clutch in our 47 works, as much as the 9-in clutch in our other car works. In my opinion, the 9-in is far surperior with regard to smoothness, ease of operation, etc.
My best to you, Bob
