Holley/Ford 94's, Holley AA-1's, or Stromberg 97's fit that bolt pattern. The AA-1 was stock on the GMC 302 for a few years, the others were found on flatties. Most people either run 2 or 3 carbs and block off the other holes, all 5 is way too much carburation for a 235 unless it can run at 10,000 rpm.
