Yah, you can use a 650, 700, 750 vacuum or dp and upgrade it with either a proform or Holley HP mainbody. Chokless, smooth entries, downleg boosters and adjustable air bleeds are the biggest benefits. Much more tunable. For 650 guys its an easy upgrade to a 750 for $150
The high speed and idle air bleeds are the numbers I listed. A standard Holley has to be drilled to make changes, generally only pricey "race" stuff has removable bleeds.
