SBC 4X2 carb set up

I'm thinking of selling this really unique turn key carb set up it was done a couple years ago by Ken Oconner he completely restores and sells intake and carb set ups his attention to detail is awesome this set with the stainless hardware air cleaners etc was around 2k turn key give or take. I've run this set up for a couple seasons without trouble on a 350ish horse SBC its and Edelbrock cross ram with 2 barrel adapters carb based are powder coated hardware is stainless with stainless bent lines fuel pressure regular included as well as linkage I'm selling it as I bought it intake to air cleaners 1200 firm a couple pics are of it new a couple I took this morning in the driveway an hour of deep cleaning before installing and itll still b really nice it works really well idles nicely. It's still on my car if someone interested ask any questions pay for it and I'll pull it inside of 24 hours clean it up and send it out boxed well shipping is on the buyer and that could b 100 bucks roughly im sure but all in this is a great looking working set up never see another like it no matter where u take ur car also comes with filler tube/breather I'm keeping the cheapy water neck. So that's it 1200 plus shipping ur prob saving a grand they're only new for a day and it does clear tall valve cover if ur running roller rockers as I am. Thanks for looking.
Also I have no clue how they calculate cfm but Kens feeling was that it flows around like a 650 carb it runs great sound great never too lean and linkage is fully adjustable when back carbs kick in.
