Intake manifold identification

[71VERT]

I am trying to figure out exactly what I have so I began checking the casting numbers and found the intake to be a winters aluminum manifold with a casting # of 14044836, I knew it had a different carb on the car, which is a holly 3310-2 ( 4160 model ) 750 Cfm, The block id's match as well as the engine casting # 3970010 is correct. It is a smallblock 350/270hp. 1971. Does anyone know what this manifold was originally for? I do not think it is the original.

Thanks
Jerry

It's an over-the-counter GM Performance part - the original for your car is casting #3973469, cast iron, for a Q-Jet.
