80 volare suspension swap into dart?

Well, the big deal with the swap is my dart has a v8 k-member. Slant six members are different right? I don't have a slant six k-member and thought the volare swap might be easier and cheaper. Talk about a poorly planned plan, LOL. I have a 318 ready to drop in with 360 49cc heads and intake that should run fairly well on a stock 318 bottom end. With the heads it should bump up the compression to 9.8:1.
