Average Torque
If you could only use one factor to rate these manifolds, this would be it. What we found interesting was how the very-short Torker II manifold lived up to its name, making 19 more lb-ft than the Victor Jr. at 3,800 rpm. Also, note that in the middle of this ranking (Team G through the Hurricane), there are 10 manifolds with barely 7 lb-ft of torque between them, so it would be difficult to feel the difference in power between these intakes. The top five manifolds are covered only by a spread of 1 percent average torque.

Average Torque Per Dollar
Next, we combined the two most important test criteria to rate how the average power was affected by price. Think carefully here, because the least expensive manifold is not necessarily the best buy; for example, the top two manifolds here are the worst in terms of overall power. Assuming power trumps price, then the Summit manifold really shines, as it placed mid-pack in average torque and is attractively priced at only $189.95, making 2.53 lb-ft of torque for every dollar spent. The next best manifold is the Holley Strip Dominator, which made more torque but costs an additional $30. At the bottom of the category are the Wilson and AFR manifolds with fractional numbers because their cost is higher than their average torque.

Carb Pad Height
This is a simple evaluation: The manifold will either fit under your hood or it won't. The carb pad height measurement is the distance from the carb-mounting pad to the bottom of the rear china wall where the manifold seals to the block. If you already have an engine in the car, you can measure your manifold and compare that height with any of the manifolds tested here. One technique to check fitment is to place a lump of soft clay on top of the air cleaner at the closest point to the hood. Then close the hood carefully and measure the height of the compressed clay to determine the clearance. An interesting result here is how well the Weiand Team G and Victor Jr. manifolds performed, considering their attenuated height.
