6-pack intake manifolds

I bought a complete 340 Six Pak setup back in the late 80's when I stumbled on it thru my work. I work for the power company and had an order to fix a yard light at a garage. I fixed the light and went in to tell the dude I got it taken care of, and there sat a 340 Six Pak setup against his office door. It was apparently off of a Mr. Norms GSS Demon or something, because it had one of those junky little open element "Tri Power air cleaners on it. I told him I fixed his light, and asked what he wanted for the Six Pak setup....and he said $20 and a cinder block. I asked what the conder block was for, and he said "The same damn thing that hunk o junk has been doing for 20 years.....holding that F'n door open!" I gave him $20 and went and found a cinder block! :D I went thru the carbs, and put it on the 340 in my Challenger conv when I got it done, and it ran good. Went 13.20's in that lard *** car with street tires and mufflers. I ended up pulling that motor out and selling it. It went to Tulsa, OK and supposedly ended up in a Dart.
