I just pulled the manifold from the shelf and it's an Edelbrock Victor 351AHII part # 2990. This is the one for high port SVO heads, 9.2" deck....
It has previously been drilled and tapped for nitrous or vacuum lines, which you could plug if not required. It also has two small tapped holes (not penetrating through) on each corner of the side of the raised carb plate. It looks to have been polished at some point and would shine back up with a little elbow grease. I see it retails at $425, but I have no use for it so $125 + shipping and it's yours.
Drop me a PM with your e-mail address if you need more photo's.
