Reply to "intake questions"

First, the rpm ratings are not exact. Second, what they're really talking about is street driving vs drag-racing or open-track work. An open-plenum intake paired with a 750 cfm carb will be fine if your engine spends most of its time above 4500 rpms. If you only occasionally go fast but spend most of your time at legal speeds in traffic, you and your engine will both be more comfortable with a "street" intake; that is, a dual plane. This's why there are a number of open plenum intakes for sale cheap but not many dual-plane Edelbrock Performers, IMHO one of the best street (and light competition) intakes available for a 351C. A Performer runs out of breath around 5500. If your engine is fully built-up with a fairly radical cam & a big carb etc and you enjoy running it above 6000 for long periods with no regard for tickets or gas mileage, an open plenum type intake is for you.
