5.3 or 6.0

[Blasphemy]

I guess im the dummy who boosts a 4x4.. o well fun pulling on vettes

and idk about hitting 400HP with a ls2 cam. mid 300's sure but its gunna take a good head/cam combo to tackle the 400 mark.

I guess it all depends on personal preference. I would boost the shit out of a 6.0 or 5.3 with a set of twins if it was in a single cab shortbed 2WD truck, which I plan to do someday. But why spend $5K-$7K on a boosted setup when you can build a badass long block for that price with all forged internals? A supercharger would be a good middle ground because it makes good reliable power in the earlier RPM ranges and it doesn't require an engineering degree to install like a turbo setup!
