For a large displacement small block with 210cc heads which intake would you use and why? Looking for good idle to 5000 rpm power. I like the looks and overall package of the Pro Flo intake but it may not be what I need.

Just offhand, it seems to me like the ProFlo fits your bill, especially since you want the power from idle to 5000.
I have no experience or knowledge of that manifold, but it appears similar to an LT1 manifold, except for perhaps longer runners. And unported LT1 manifolds are feeding 600 hp strokers over here in our "two ton racing classes" :)

Thats what I was thinking too but I was recommend going with a dual plane air gap intake from what we will call a 3rd party. First of all they don't even make a dual plane manifold machined for injectors and second of all it would suck.

I read somewhere this intake has 5 inch long runners. Those 5 inches plus about 3 inches of intake runner length in the head should keep some decent velocity going I would think. The intake system is rated up to 650 hp with 44# injectors per Edelbrock. Should be plenty substantial I would think.

I think the pro flow would choke your heads flow in the upper rpm's. You said a big cubic inch small block with 210cc heads that is alot of air. What size are you talking about

400 small block that will never see anything past 6000 rpms. I'm looking for strong lowend torque and once the turbo spools if there is any chance that intake is a restriction NA it won't be once there its under boost.
