Professional Products Hurricane It was difficult for us to tell a difference between the Hurricane, the Hurricane Plus, and the Super Hurricane manifolds. The Hurricane tested the best of the three and is the least expensive! PN 52031 Price $210.95 Peak HP 536 at 6,400 Peak TQ 511 at 4,600 Average TQ 484.9 Carb Pad Height 5.87 Plenum Depth 4.49 inches Wilson Ported Super Victor 23 We expected the Wilson to perform very well, but it appears that its limited height kept it from the top-horsepower brass ring. Compared with the Super Victor II, the Wilson ported Super Victor is 1.3 inches shorter in carb pad height. If cost is no object with a cast manifold, this is the place to be. PN 128-250 Price $901.28 Peak HP 540 at 6,300 Peak TQ 513 at 4,700 Average TQ 488.9 Carb Pad Height 5.50 Plenum Depth 4.05 inches Racing Head Service The RHS intake is unique in that it is machined for three different small-block intake patterns: the standard 23-degree small-block, the '87-and-later pattern that uses the near-vertical center bolts, and the '98-and-later Vortec 8-bolt version. This manifold is able to accommodate all three of those cylinder-head choices. Plus, the multi-point EFI version aims the injectors toward the back of the intake valve. PN 12902 Price $299.95 Peak HP 534 at 6,300 Peak TQ 511 at 4,700 Average TQ 486.0 Carb Pad Height 5.50 Plenum Depth 3.92 Holley Keith Dorton This manifold was among the sleepers in this test. It produced excellent average power and good horsepower. PN 300-110 Price $279.95 Peak HP 538 at 6,200 Peak TQ 516 at 4,700 Average TQ 487.6 Carb Pad Height 6.10 Plenum Depth 4.80 Holley Strip Dominator The word on the street has it that the Holley Strip Dominator was a good piece, and our testing substantiates that claim. It's also among the most reasonably priced tall manifolds. PN 300-25 Price $207.95 Peak HP 543 at 6,200 Peak TQ 514 at 4,700 Average TQ 488.2 Carb Pad Height 5.71 Plenum Depth 3.97 inches Edelbrock Super Victor II If carb height is not a problem, there is little to dislike about the Super Victor II. Combine excellent horsepower and torque from an as-cast manifold, and you have the makings of an out-of-the-box winner. We'd like to see what Wilson could do with this manifold. PN 2892 Price $379.95 Peak HP 549 at 6,300 Peak TQ 516 at 4,800 Average TQ 490.9 Carb Pad Height 6.80 Plenum Depth 4.57 AFR Titon The Titon is the only composite-material manifold, but it can be easily converted between two different plenums. We tested the taller of the two optional plenums, and it's still more than an inch shorter than the Edelbrock Super Victor II. PN 4801 Price $581.03 Peak HP 541 at 6,300 Peak TQ 519 at 4,600 Average TQ 492.2 Carb Pad Height 5.64 Plenum Depth 4.01 inches « | 1 | 2 | 3 | 4 | 5 | 6 | » | View Full Article By Jeff Smith Enjoyed this Post?
