Barry Grants operation went out of business about a year ago. Holley bought what was left and has started to produce some old and some new Demon carbs. The stuff sold during the last part of Barry Grants ownership had some serious quality control problems. I think some of the features were nice but the final product varied from usable to junk depending upon how bad the machine work was that BG let get out the door. Having seen and paid for some of the BG junk myself I wouldnt buy any of it without a money back deal if it didnt run right.
