34's are nice and will give it a boost with your chambers and 72 cylinders with the higher transfer cutaways.........depends on what shape they are in I guess.......I have a set of sled carbs that looked pretty well used.......at $99 a peice for new ones VM34-168's from Niche......I just got new ones............the UFO's are made out of a pretty hard or tough nylon or plastic if you make them.......probably so you won't strip the screws when you mount them.............if you go with 34's and UFO's.........this jetting will at least get you in the ball park (at the end of the post)........same that Ron and I use (67Lotus49 in California)
