Default LS2 or LS6 Intake Manifold???

LS2 or LS6 Intake Manifold???

You have a deal on both.. which one do you get for an upgrade for your stock LS1... planning on porting which ever I get?

Thanks for the reply... anyone have experiences on theses with Dynos? In the FAR future planning on supercharging, getting the ducks in a row until then piece by piece.

LS6 performs better and accepts your stock throttle body

LS2 is a downgrade in manifold, but you will have to use the bigger throttle body

I was faced with this same question, LS6 is the winner

Have an LS1 like you and am going to put on LS6 intake this winter with a few other nice mods this winter. Hope to be about 450 rwhp when done.

I had heard that the LS2 was a better choice if you plan to do heads and cam etc. For a fairly stock LS1, the LS6 is a better choice, but once you start running more HP, the LS2 is the choice. Was I mis-informed? Is there any counterpoint to this? I plan to do ported 243 heads and a fairly aggressive MTI cam, and have been questioning what intake to run.

Good choice. Do the Z06 pcv valve conversion too while you're at it.

Misinformed, the LS2 does not flow as well as the LS6
