Local Pantera guy has had the Crane Rocker Arm kit on his Pantera engine for at least a decade. This includes many track days at various facilities. He has never had a problem with the kit. I too was skeptical when he installed them. However, I am no longer.
So are these concerns based on known failures or well intentioned engineering hypotheticals?
...I'am NOT Concerned! It's NOT MY Engine!!
Hypotheticals? No! More like 45+ years of Machining Practice. I 'Think' I know Steels and Heat Treating along with just a 'little-bit' of knowledge In Physics and Engineering. LOL The 5/16' end, where it meets the Flange of the 7/16" Stud, 'barely' has any kind of a Fillet, at all. Not to mention the 'Sharp' Thread of the 'Minor Diameter'. OK, It did not snap on the First Day. But the man is racing on Borrowed Time. I'll take your word for it, that the engine has seen racing at higher RPM's.
The One thing I Do know is 'The Harder You make Steel, the Closer You get to the Brittleness of Glass!'. Here, I'am Not going to get into Annealing and Work Hardening.
When building Engines, I Believe in 'Massive Overkill'!! It'll Never be 'TOO' Strong. My point being...Why would anyone want to build a Cleveland Engine as WEAK as Possible?? And for Racing, No less?
So, go ahead a defend the use of these parts, I would love to see YOU put them in YOUR Engine!! Now THAT would Prove your No longer skeptical, and Not just BS'n.
