I watched a video of a comparison between the manifolds. Don`t remember where or who, but the engine cleaned up and ran better w/ a single plane. My throttle body is bigger than a dual plane opening, no question for me ! Not arguing w/ anyone that, "I`m sure knows more about it than me" ! My setup is a fast 2.0 , I haven`t had any of these problems, and Dave and the guys at Fast (comp cams) have been very friendly, and answered all my questions/ great tech support. Yeah theirs is a little pricey, but comes w/ everything needed for the average install., no need to go hunting corvette parts or anything else. the biggest thing is their timing controlled dist. is based off a chevy, and very short. It requires a but load of clearanceing if u run aftermarket alum. heads. Not that this has anything to do w/ u, but I`d go single plane anyway if it were me,--- JMO.
