I have a realeve ls3 427. Going to run Texas speed ls3 cnc heads. What intake are u guys running with ur high cubes ls3. Was looking at this Texas speed intake but haven’t found anyone who has ran it yet.
What are you going to be doing with the car? The factory intake is pretty damn good for a balance of HP and TQ. It can also handle pretty good boost levels. The intake you pictured is ok but I think a bit of a waste unless you are building a high RPM/HP engine or will have a lot of boost. There is no "best" intake manifold to fit all situations. Figure out what you are doing with the car and go from there.

If budget is not an issue get a Tony Mamo ported Fast 102. I looked at his ported and new there close to $2K, every dyno result I've read shows nice gains over a OEM LS3 intake.
A Gwatney ported/rodded LS3 intake at $675 is better than an OEM LS3 intake and almost as good as a ported FAST.
