Anyone have un used project parts

Hey guys I got fabo cause I'm building a big block 72 Dart. Well for the last 6 months I have been having health issues. I'm diabetic and have been for years. Starting having a lot of complications. Been so sick. Lost my job of 29 yrs because of it. I want to build a 500 inch b block. I have a solid lift roller for it. I was going to put the TFL 270 on it. Well my budget has now dropped dramacticly . I have so many parts now . but I don't have a stroker kit. And I don't have heads. I pretty much have everything else. I have a 440 block that's been grouted. I have another complete 440 and 727 still mated together in my garage . and I a virgin 400 short block. I think I can make the same or close to the same power with a 451 or a 470. So what I'm asking is . does anyone have a stroker kit for any of the 3 engines I've listed that they would like to sale. I would love to build this motor if I can afford it. Asking for any help. Would love to buy all new stuff. But they may not happen. I have decided to drop down to the 240 heads instead of the 270. Just need to build this motor on a major short budget. Any help would be greatly appreciated.
