Super six van

So I finally got to check out one out of the two vans I may be picking up. it looks good and from what I hear the other looks about the same.
So I pop the hood and it is the six like I was told. So I go inside the van and the lid for the motor was already opened just not taken off. So I pull it back as far as I can and use my lighter for light and in the intake cleaner it says super six. Next thing u know I'm pulling the lid so I can look down into the carb and it really is a 2bbl. Woo hoo I'm in luck. I'll be checking the other van this weekend. Let's hope it has the super six as well cause in taking the SS intake manifold and carb and hooking it up in my dart. I'm hoping both are as as I plan on fixing one van and selling it then parting out the other unless it shows promise. If so I may get it running and either sell or keep it. Probably sell it tho. The guy selling is trying to get 400 for the pair which ain't bad but my buddy said the owner is only wanting 100 for the pair. I dont mind paying the middle man some cash but not 3xs what the owner is getting. I'm gonna try to talk him down or I'll go straight to the owner. I may give him up to 300 I know I'm a tightwad but I wouldn't up the sell on someone like that even if I didn't know him. Especially when they would also have to deal with the owner but separately. Am I wrong for that.
O well anyone else see the SS in a b100. These are owned by a sheriff or ex sheriff so I was wondering if the don't come stock like that maybe it's a police package or someone added it. If they just came stock like that I'm surprised more haven't noticed em
