HI,I was just wondering.D&D sells a complete swap kit for various engines into 79-93 foxes. I was wondering on a 351w or clevor, or 429/460 swap into a 94 v6. The kits come with headers,so I was wondering if there were fitment issues to use the earlier headers. I know you guys like efi but I was thinking carb as I wouldn't have to buy the wiring,computer,injectors etc.
