Intake Manifold

[srfinatsunset]

I was pulling the carb to get cleaned and tuned up along with distributor cap and rotor, and the vacuum advance. I took a few pictures when I was in the area.

I saw the number on the intake and it was a 3883948 GM1. A quick search says it's a off a 66-67 Vette, Camero, or Chevell. I get it may not be the the original motor but it's 454 with a Rodchester 4 Barrel. Can anyone tell me what style intake this is? Oval, rectangle, worth keep on there. Is is a good intake for a BBC? Is it worth keep it on there?

I do have a Weiand stealth oval port but it had a Holley carb on it. Will it work with a Rodchester 4 barrel?
