SBC Mopar Single Plane Intake Manifold (P4452893)

@rumblefish360

I have a quick question. How do I tell if this intake is a W5 or W2? ie. what does W5 and W2 actually mean? I saw your other forum post about this intake specifically but had trouble understanding exactly what the result was. Basically I have a lot of in inquiries about the intake but I'm an amateur in this department. Any help would be appreciated
