Summit Single-Plane Be sure to note this manifold's place in the Average Torque Per Dollar category (page 24). This would be our dark-horse winner for "Tall Manifold That Rocks for Less Bucks." If this manifold won't fit under your hood, you've probably saved enough cash to buy a fiberglass cowl hood! PN 226050 Price $189.95 Peak HP 531 at 6,400 Peak TQ 507 at 4,600 Average TQ 480.5 Carb Pad Height 6.30 Plenum Depth 4.46 inches Brodix The Brodix catalog lists a bewildering number of different small-block Chevy single-plane intakes, but most are specific applications or race manifolds. The HV1000 is the most popular. Average torque is solid mid-pack. PN HV1000 Price $354.95 Peak HP 530 at 6,200 Peak TQ 505 at 4,600 Average TQ 481.3 Carb Pad Height 5.76 Plenum Depth 4.165 Bill Mitchell Products Motown The Motown intake has been around for a long time yet still delivers on the average torque and decent peak horsepower. PN 061040 Price $300.95 Peak HP 534 at 6,300 Peak TQ 508 at 4,600 Average TQ 481.5 Carb Pad Height 5.63 Plenum Depth 4.15 inches Professional Products Hurricane Plus The manifold we tested was externally polished but the part number and price indicated are for the satin version. PN 52034 Price $227.95 Peak HP 535 at 6,400 Peak TQ 506 at 4,600 Average TQ 482.9 Carb Pad Height 5.90 Plenum Depth 4.42 ProComp Shootout Pro See the notes for the Professional Products Super Hurricane. The difference in average torque between all the Professional Products and ProComp Electronics manifolds is 1 percent, which is so minor as to be chalked up to casting variations and dyno-test variables. PN 22037 Price $241.95 Peak HP 532 at 6,300 Peak TQ 508 at 4,600 Average TQ 481.8 Carb Pad Height 5.85 Plenum Depth 4.49 inches Dart Single-Plane The Dart manifold produced a strong torque curve. Its rather short plenum depth indicates that it might offer crisper part-throttle performance with its smaller plenum area. Note the strong 539 peak horsepower number.
