I have an ACC converter pn 47013 that is 2800 - 3200. I had it in my 67 C10 street cruiser for about 300 miles. I am building a 406 for it now, so I swapped it out for a TCI. It worked pretty good for me. My 350 is similar to yours. Im not trying to turn this into a classified, but I would take $100 for it plus the ride. Its just sittin around here.
