The only time I ever had a broken clutch problem, ever, was in a 52 Chrysler. I'd gone out and challenged, and lost, a 55 chevy with the duntov engine kit in it, but oversped the fuild drive and knocked it several pounds out of balance. I wasn't a fan of that M6 semiautomatic transmission, so it was time for a trip to the scrap yard, bringing home a new bell housing as that one had more cracks than one of grandma's china bowls (they were magnesium castings), and a 53 Dodge 3 speed OD tranny, and a dry clutch flywheel. The Dodge trannies input shaft fit a Ford clutch plate, the only problem bing that the flywheel was only drilled for a 9" clutch. So it wasn't until I was able to find an D-500 11" drilled flywheel that I was able to use the stronger 11" disks. The ford disk's hub was not up to the task on a long term basis, and I tore the fingers off the hub several times. That well tuned 331 hemi was a tad hard on the tranny gears too, stripped them several times but never broke the case. Never did it dragging , but puttering along in 5 oclock traffic every time. I used up every set of gears in Iowa, and in So Cal the year I was there with it, that the scrap yards had. But I discovered some gems in all those failures. In the end I wound up with a set of gears that let the straight pipe sound like a Road Ranger tranny, every gear was spaced at exactly the same ratio diff. That engine was amazing, it was the rest of the car that fell apart around it. Something north of 125k miles, one valve tuneup. I'd made some carb changes, so it got 20 mpg at 75 mph, and I'd estimate the 185 horses had been fertile, 250 hp estimated by Roger Huntingtons formula. With that traany in overdrive, it was 30 mph per 1000 revs, and I long since lost track of how many times it went the width of South Dakota with the tach sitting on 3300 rpms & getting 17 mpg doing it. One of the better sets of wheels I've had over the last 6.5 decades. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
