Any data collected on a 460 is relevant, to a 460. It is not relevant to a 440, unless you can somehow make a 460 intake work on a 440.


I disagree. My point is that often an OEM iron intake is regarded as low perf and useless. A factory intake manifold does work well in CERTAIN applications. In the application of low RPM grunt towing - a factory 4BBL intake is actually very very good. I was pointing out to the original poster that if he only had the factory intake- then he's good to go. But he has a Performer which is idle to 5500 RPM and that's a great intake as well even the regular Performer offers no improvement in power of a factory mopar iron intake. The weight savings may be important to the owner or it may not.

Keep old mopars alive.
