Probably depends on the cam whether or not stock injectors will be enough. AFAIK all trailblazers with the inline-6 have the 28# injectors.

Well I guess I could give you guys an update. I ordered a custom cam from wot-tech along with the hardened custom length pushrods a couple of months ago and I'm just waiting on my lifters and springs. I was just wondering what you guys think I should run for injectors?

So I think I'm going to go with wot-techs street/strip cam and the custom length pushrods. Can anyone recommend any other things to order that're necessary from wot-tech?

I ran a GMPP cam that was a Crane 260-2 equivalent, which IIRC is similar in specs to the Comp 260H, in my hybrid and it ran well.
