I believe that the Edelbrock 600 carb is a square bore carb... The Wiand Action Plus is a spread bore intake...

I would recommend the Wiand Stealth over the Action Plus as it's a square bore intake that will match the carb better without having to use a restrictive adapter...

Also the Wiand Stealth is rated from idle - 6800 RPM, where the Action Plus is rated from idle - 6000 RPM... The Stealth can go 800 more RPM on the top end and still pull strong off idle...

no adaptor needed. I'm running a Action plus on my 318 with a Holley 770. As I said, many choices. Action plus is cheaper and will perform great on that 318. IF a person wanted to add a 12 dollar eddy square plate, fine. Sell them at any O'reilly's or ebay, etc
