Are you able to put the intake manifold off a 392 on a 2008 Dodge Charger RT?
Now for YOUR car, different story. Your heads are much more related to 392 heads, bigger valves, larger ports on an engine with alot more cam and compression. You also wouldn't need to space it to clear anything like a pre-eagle engine would. Even without a cam you'd see benefits, a cam would make them just that much better. Just make sure you swap out the 392 injectors for your stock eagle 5.7 injectors (which are also stock for the 6.1) as they'd be overkill for your engine.I’d be curious about this for my 2011 R/T too. Seen a YouTube video swearing by the 392 on the 5.7 🤷🏼♂️
