Trailblazer straight 6 cylinder Engine

[tgvettes]

Has anyone done any work on one of those? I thinking about using one in a pretty lightweight car that will be different.
I'm probably mostly looking at if someone have ported the head on them and maybe other camshafts. I have not seen any info about this engine out there but to me it gives a pretty decent power output in stock trim. I was thinking of getting it up to maybe 330-350 HP with no cat free flow exhaust, some headwork/camshaft and tuning.
