Motor is HOOOPEDDD!!!
Started it up at work today and have the worst rod knock and lifter tick ever...
welll u know what that means.!
oh and by the way Everyone on the v6 forum..
my truck just rolled over onto 19,000 Miles.. this is proof that BOOSTING A V6 IS A BADDDD IDEA!

That post awesome. And off base, and on amphetamines. Reciprocating internal combstion engines are better engineered than ever before. They are not throwaway. They are not cheap junk. Things lasted longer in the past because the science and engineering of failure probability was inaccurate. So, "When in doubt, make it stout" was the order of the day. Thicken those cylinder walls by 10% just to make sure.
Nowadays, engineers are amazingly good at predicting failure. It's literally what makes aircraft travel possible. Knowing when an engine will give up, or start exhibiting component failure, enables you to eliminate extra material (aka cost) wherever possible. The result? A strong engine that costs less.
Now if an engine costs less, then the break-even point between a labor intensive repair and a replacement drops. A new Hemi might cost Chrysler $2000 for round numbers. A week in the shop to rebuild a motor that threw a rod might be twice that in warranty claims.
These "throwaway motors" are actually engineering marvels that cost everyone...consumer, garage, and manufacturer, less in the end. If there is ANYTHING a large auto company does NOT want to do, it's under-design an engine that loses money on warranty work and catastrophic failures.
Know what the design has to do. Design it to those exact specs. Test the crap out of it and know how and when it will fail. Reduce cost where possible. Test again. Repeat until the design is optimized. That is true mechanical engineering.

how?
So could anyone describe to me exactly what happened to make it die like that? I don't get it.

in short, it went like this...
High comp motor + boost = MUCH more stress on stock internals and possible bent rod with premature engine failure.
No, this is proof that boosting a STOCK V6 is a bad idea.
