Not sure why people don't like the Holley, or Holley-clone carbs. I find them much easier to work on than any other type. Of course maybe this is because my 1st car had a Holley "780" #3310 on it. That was in 1973. I have the same (newer) #3310 Holley on my 340. No problems at all, runs great basically "out of the box".
