6.0 vs 408 Stroker
Callies CompStar cranks are made in China but machined & quality checked in the USA last I read. Have two LS's with CompStar stroker cranks both were first rate quality.
No idea on Oliver.
Summit probably is similar to Callies CompStar

You have literally the perfect turbo engine candidate already in your truck, a couple of pipes and a VSR turbo can easily make a ton of power, double the 408. Heavier the vehicle the more the turbo wins the argument, heavier just puts more load which makes spool faster. An NA 408 is going to feel like a dog in a 5500lb vehicle, first time the turbo spools you are going to absolutely enjoy the fact that you didn't waste thousands building a 408 for hundreds less horsepower.

I too would stick with a mostly stock LC9 and add a little boost. Save yourself the time and headache of swapping engines or buying a new rotating assembly.
A stock LC9 with a mild camshaft and a VSR billet 62/62 would make more significantly more power and torque than the 408 in a vehicle that heavy and you can do it all without ever removing the engine.

Well my only concerns with that is longevity/reliability and the 225,000 miles. That's one of the big factor to staying n/a. I can't see what can go wrong or cause headache after swapped in. Knowing my luck I can see spending the money and time for a turbo, cam, fuel system and then it blows up after a handful of pulls. I'm already swapping the trans and tuning it so I would do an engine at the same time. Kill two birds with one stone.
