How much boost on stock plastic intake? Building a forged 6.0 with ls3 heads. Thanks for the info

Sooo why not just ask several questions in one thread instead of 1 for each part?

The intake and crank will be fine for a good bit, unless youre shooting for 1k+

LS6 intake is different. It's for a cathedral head and it's a one piece design. Not sure about the LS3. I suspect the comment about not making over 1K hp is because of the heads unless he intends on using an aftermarket LS3 style head like the ones from Mast or PI.

We saw 30psi on my LS7 intake during tuning. Don't plan on going there often but it has held up fine.
