Agree with both of you, but consider this: The '01 - '10 Duramax and Allison has been modified extensively, yet NO ONE is bad mouthing the quality of those, or GM for not covering obvious racing damage. Ford should have made a better quality product with the 6.0. I know there are many Allisons that have been limped or destroyed, but customers understand it's because the power is doubled, and the engines are still not blowing up left and right. I always gave GM tremendous credit for building products that were reasonably reliable even severely modded, and now I say: gay move GM lol but I understand. People love performance and modding. My 63 year or stepfather has a build LMM, and he will never buy and LML...
