Unless you're going to go with a big cam and different heads an Edlebrock dual plane will flow better than a stock intake unless you port match the stock intake it to the heads. I have a Performer 289. After installing it, it was a distinct improvement over my stock cast iron 4V intake. There are better, more expensive dual plane intakes. It depends on what you intend to do with your motor down the road. If you plan on keeping it stock an Edlebrock, Holley, Weiend, etc. dual plane will wake up your motor, so will port matching the intake with the heads and the heads with the exhaust. But just for a bolt on solution would be a dual plane alluminum intake with no more than a 500CFM 4V carb on a stock motor.
