Jeesh. I have learned over the years when people attack people, they have run out of ammo.
Of all the LS-7 engines I have worked on/know of around here, 1 engine broke 1 valve spring.
I would think if 1 out of 20 failed, there would be Vettes up on blocks all over So Cal., or Diane Sawyer would report it on World News Tonight.
As for CF, those guys are more authoritive about cordinating floor mats and fuzzy dice than engines.
I would also expect a machine shop to have broken parts, as most people do not rebuild engines that are working fine.
Hope this helps Ben.
