Intake Casting #14057055

Hi,

I'm new here. I am in the process of going through some parts that came with a truck I bought (A LOT of parts.........), And I've been looking up #'s online for the casting numbers to find the values of some parts I have.

I came across an intake manifold with the Casting number 14057055, and looked it up. On here, a guy said he sold one to a chevy dealer for $700 (Not sure if he said it with sarcasm. If so, I'm gonna feel like an idiot. LOL), and a guy sold one for close to $400 off Flea-Bay a while back too.

Is there anything behind this intake that would make it that valuable? I've seen the words "crows foot" tossed around. is that the thing that looks like a crows foot on the back side of the Carb mounting flange?

Thanks in advance. I'll probably have more questions as different parts come up. I'm only a teenager, and don't have a lot of knowledge with vehicle parts, and their value. But I'm always eager to learn new things. :D

Again, thanks a bunch.
