Six Pack question

You say never installed ?does that mean the carburetors are brand new? that looks like an original factory TA manifold to me. I'd like to see more pics. Nevertheless congratulations you've joined a small group of badass small block mopars
The intake is the very last style offered by Mopar Performance. No way no how a T/A manifold. The last ones were made by God knows who and can be spotted easy by the 2 machined area's I have outlined.
