gains of 36hp on average are not impressive? on a stock vehicle no less.
i agree, there didnt seem to be much torque gain, but there is likely an explanation for that.... like perhaps the ls6 intake gives kick *** torque already?

I'm glad to see this product, but it has all the technology of a tunnel ram.
If you cut this apart and a LS6 intake the OEM has a lot more tuning for velocity and distribution. I'm guessing low on torque for a small cam 346 street car below 5K rpm.

Why would you want to shorten the runners? DO you have something against low-mid range torque? Besides that, shortening the runners would defeat the purpose of this intake. IF you wanted a top end (rpm) manifold, why not go with a Vic JR, or Super Victor, or that new tuned fiber intake, or a gm carb style intake, or etc. etc. There are lots of intakes with shorter runners for higher rpm to choose from.
