3000 RPM Stall, What Intake Manifold/Powerband?

All,

I need a new intake manifold as my Cobra manifold is cracked and broken.

Mods are in sig, but in brief, I run:
stock heads/cam
stock bottom end
4.10s
3000 RPM lockup torque converter
125 shot of nitrous


Now, I'm tempted to go with an intake manifold with a 1500-6500 (Track Heat, Typhoon) powerband because of my 3000 RPM stall speed...but, will this cause a flow issue and loss of power with my stock heads?

Would I be better off with an idle-5500 manifold (Street Heat, Eddy Performer)? If I wasn't running a 3000 RPM stall this would be a no-brainer.

Basically, will a 1500-6500 manifold create a loss in horsepower above 3000 RPM for my stock headed/stock cammed car? Or will it only hurt down low and make MORE power up top than a 0-5500 RPM manifold?

All searches of the forums have yielded is that the 1500-6500 manifolds lead to a loss in low end power...which isn't a factor for me because my car stalls at 3000. I want to know how it effects performance above this for stock headed/cammed cars.

Input is welcome. Thanks.

Thanks for the feedback. This is the kind of information I'm interested in.

One question, isn't the Holley even shorter runner/higher powerband than the TFS Track Heat/Eddy Performer RPM? I was under the impression that the Holley that Rio94GT went with was more comparable to the RPM II?

Anyone else care to comment?

One things for sure: Anything has got to be better than the POS stocker! I never realized how much the Cobra manifold helped until I put the stock one back on...wow, the car feels SO slow right now.

The short runner intake don't shine until you have the heads and cam that will allow the engine to pull into the 6000rpm range. Until then their design can actually have a negative effect.

I'm going to assume that everyone is in agreement about this (especially the part in bold)?

Looks like I'll be going with a Street Heat intake then...

Too bad, because the Typhoon is SO cheap.

Well, I ordered a Street Heat intake from Summit! I'll post the results after it's installed.
