Offy intake

So I went to a vintage drag race last weekend and bought what I was told was the correct intake for my 1965 383..... Long story short I'm newer to the big block scene and the guy screwed me and sold me an intake for a 440. So would anybody want to trade an absolutely immaculate Offenhauser 360 intake to go on a RB for a decent (even if it's a stock 4 bbl) square bore intake for a B?
