> The "Machine" intake is a cast iron > copy of the Edelbrock R4B. > From Performance American Style circa 1972. This isn't correct, the Machine intake does not have the same dimensions as the R4B. The R4B is taller, and the Machine air cleaner assy won't fit, it will hit the hood. As a result the Machine intake is better below 5500 rpm, while the R4B will pull stronger out to 6500. The general consensus has been that the Edelbrock Performer is a copy of the Machine intake... Dave -------------- next part -------------- An HTML attachment was scrubbed...
