Warrior vs Northwind Intake?
In the search I can't find any comparison between these two intakes, has anyone ever back to back tested them on a moderate bracket motor? Are these two intakes pretty much interchangeable? In my case, I'm running a Northwind on my 11.25:1 E85(now) high altitude motor (1978 T/A in my signature).

The old Warrior single 4 bbl intake and the Northwind Intake.
The Northwind intake might beat out the Warrior single 4 BBL intake on the typical 421/428/455 engines. The old Warrior intake suffered from a small intake plenum due to being designed for a Pontiac 366 cid engine. Most5 had some sort of a spacer added to the flange to help the intakes gain more plenum volume. Some of the intakes looks stock under the "shielding" added as the plenum volume was added below the stock intake floor. Hopefully the Northwind intake has a plenum volume designed for the larger engines and can feed the runners properly. My vote would be to use the Northwind intake but I have never seen a dyno comparison of the two 850 style single 4BBL intakes. Post up if you are aware of the plenum mods on these intakes or ever saw one modded properly. Tom V.

The north wind has a more consistent expansion rate from the flange back into the Plenum then the warrior / Doug Nash Intake.
This will provide a motor with a wider power band and one also not as peaky as the Warrior. With the Intake flow rate of your heads I would still try and run as much spacer height as you can with the Northwind.

I have a Northwind done by Dave Wilcox, he said it would work good for my application. He did a set of HP’s at the same time he did the NW, for a 480 build I have planned. Here are the flow numbers he reported. The reason I went with a NW is to fit under a second Gen F-body shaker. And Dave said he could get a lot out of it, it’s a good intake.
.4 291 .5 344 .6 385 .7 409 .8 414 .85 414 .9 406 Flows 398 with the manifold on it @ .800.

Flowed a nw attached to a 300 cfm head ,lost nothing. In flow.Until carb was installed did i notice a loss but regained loss flow with a 1 inch spacer.Nw port roof is too shallow to the entrance.Its kind of like a victor cut down .500 it will lose flow due to the reason

Though the 4500 flange will flow alot better at the roof without spacer

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
