For intakes to fit your criteria, the two choices are the Indy dual plane or the Mopar 337, which is no longer produced so you’ll have to hunt for one.

For a street car, I’m not of the “run all the lift you possibly can” mindset.
You don’t need .850” lift in that type of application.
Do yourself a favor, and keep the lift and ramp speeds within reason, which will allow you to run lower spring loads, and when the right combination of parts are used..... the reliability is pretty good.
I’m talking solid roller here.

That’s what I’d use if the goal is really 650+hp.
