I had the old/new flatty out this weekend and found my first weak point. I'd like to know if you all think this might be a fluke or something I'm gonna be doing all the time. I've ordered the new replacement gear and I'm planning on having the whole case Cryogenically treated. They boast a 30% improvement on tensile strength and 100 percent on wear. I read a few old threads on here about the D18 surviving 400 horsepower and small V-8's, and I'm nowhere near that realm. Did I just have a bad day with this one?
