Scored Offy dual quad intake for my 392 WEDGE project!

Howdy. Long time moparts member here but new A bodies member. Im glad and sad I found this post. In 2002 I bought a brand new Offenhauser 2x4 from Summit. Its for the later 273 not the earlier oddball mounting hole config. I have been buying and storing parts for my 360 Demon since 2003. My child support obligation is concluded in 2 months and I am actually moving fwd with my Demon. (Note I sad child support obligation not father obligation). I knew the 273 manifold would not be optimal on a 340/360 but want that early 60s nostalgia none the less. MiradaMegaCabs post mad think oh s#@!. If I cant make the 2x4 Offy work then Ill probably do an RPM and a Street Demon carb but man! My goal is a daily driven near manit free Demon capable of low 13s in street trim- so I would hate to run a Weiand tunnel ram on a 13 sec car. (Six pack too expensive!!) I was actually awaiting Edelbrocks release of their 500 cfm AVS2 so I could purchase a pair of them. Part number 1902 is due out march 6 2018 but keeps getting pushed further out.
