Yes mike moore. He has been doing some ls swaps. So he makes motor mounts and headers for scout ii swaps. They come with a jib you bolt to existing motor mounts and slide the new one over and weld on. No measuring etc. The headers are stainless with heavy 3/8 flange I believe. 425 for everything. Manifolds on carparts were bringing 75 bucks each when I checked. So for a little more money I went this route. Should gain hp and save time and headaches fabing up a universal mount. Don't know if they would work on a 800 though. Will post some pics when I drop the motor in this weekend.
