Intake manifold: Torker 340 vs dual plane

You have a snappy cam, decent gearing, and a slippery convertor. The torker isnt "junk". It works in the applications it's designed for. Your's is close. The RPM or Air Gap are designed for wide rpm ranges, starting from just off idle. Depending on size of the engine, they may rev well over 6500 and make more torque in the ranges you drive in. (idle to 3500 or so). The Torker sacrifices low end torque and low rpm response for more total power, and usually more torque, but at a higher rpm peak, and not as flat a curve. If you do a lot of driving below 3000 rpm, then the RPM or Air Gap will feel quicker, and be snappier where you normally drive. So it would be a "better" intake even if the total power is slightly less. (Not all engines like single planes, but in most cases, they will make slightly more overall power)
