The LSx platform is good and the Bowtie boys are lucky to have it, as are the blue oval guys lucky to have the coyote. And here we are stuck with that darned ol Hemi. So it needs a few aftermarket parts to make it reliable in extreme applications, the block and heads are up to the task so the foundation is there and hopefully the engineers are taking note and some of these weak spots will be addressed in future upgrades and Mopar Performance parts. I am plenty prowd of what we do have. No I would never put a LSx in a Mopar or a hemi in a 55 Chevy.
